Description
Stabilisierungsmittel für Polyamide Es ist bekannt, Polyamide gegen Alterungserscheinungen, die unter dem Einfluß von Wärme, Kälte, Sauerstoff, Feuchtigkeit und Licht auftreten, durch Zusatz von Alterungsschutzmitteln zu stabilisieren. Hierfür wurden schon z. B. chlorhaltige, stickstofffreie Verbindungen, die phenolische Hydroxylgruppen enthalten, und deren Derivate verwendet.Stabilizers for polyamides It is known to counteract polyamides Signs of aging under the influence of heat, cold, oxygen, moisture and light occur, stabilize by adding anti-aging agents. Therefor were already z. B. chlorine-containing, nitrogen-free compounds that contain phenolic hydroxyl groups and their derivatives are used.
Zu diesen Verbindungen gehören die Monoäther von Brenzcatechin, Resorcin oder Hydrochinon, die am Atherrest oder am aromatischen Rest oder in beiden noch andere Atome oder Atomgruppen, wie Halogenatome, enthalten können, ferner Phosphorsäureester von Chlorierungsprodukten von aromatischen Polyoxyverbindungen, z. B. von Brenzcatechin, Resorcin und Hydrochinon, sowie sek.-Hexyl-2-chlor-4-oxytoluol. Diese Verbindungen werden den Polyamiden in Mengen von etwa io bis etwa 30 °1O zugesetzt. Solche Zusätze wirken nicht nur als Stabilisatoren gegen die Alterungserscheinungen, sondern auch als. Weichmacher. Dadurch werden auch die technologischen Eigenschaften der Polyamide verändert, was für viele Anwendungszwecke nicht erwünscht ist. These compounds include the monoethers of catechol, resorcinol or hydroquinone, those on the atomic residue or on the aromatic residue or in both may contain other atoms or groups of atoms, such as halogen atoms, and also phosphoric acid esters of chlorination products of aromatic polyoxy compounds, e.g. B. of catechol, Resorcinol and hydroquinone, as well as sec-hexyl-2-chloro-4-oxytoluene. These connections are added to the polyamides in amounts of about 10 to about 30 ° 10. Such additives not only act as stabilizers against the signs of aging, but also as. Plasticizers. This also increases the technological properties of the polyamides changed what is undesirable for many purposes.
Es wurde nun gefunden, daß man die Eigenschaften von Polyamiden verbessern und insbesondere die Alterungserscheinungen besonders nachhaltig dadurch zurückdrängen kann, daß man den Polyamiden vor, während oder nach ihrer Herstellung halogenierte Di- (oxyphenyl)-methane zusetzt. It has now been found that the properties of polyamides can be improved and, in particular, suppress the signs of aging in a particularly sustainable manner can that one halogenated the polyamides before, during or after their preparation Adds di (oxyphenyl) methane.
Da die stabilisierende Wirkung dieser Stoffe schon bei Zusätzen in Mengen von etwa o, x bis etwa o, 5 °/o eintritt, werden die technologischen Eigenschaften der Polyamide im übrigen nicht beeinflußt. Die erwähnten Zusätze lassen sich besonders leicht in die Polyamide einarbeiten, und die Polyamide sind danach sehr gut verarbeitbar. Since the stabilizing effect of these substances even with additives in Quantities of about 0.5% to about 0.5% are the technological properties the rest of the polyamides is not affected. The additives mentioned can be special easily work into the polyamides, and the polyamides are then very easy to process.
Wenn man die erwähnten Verbindungen vor oder während der Herstellung der Polyamide, z. B. vor oder während der Polymerisation von e-Caprolactam, zusetzt, so wirken sie außerdem noch regulierend auf die Durchschnittslänge der Polyamidketten, so daß man Produkte mit einem geregelten mittleren Molekulargewicht erhält, wie sie z. B. zur Herstellung von Fasern erwünscht sind. If you make the mentioned connections before or during the production the polyamides, e.g. B. before or during the polymerization of e-caprolactam, adds, they also have a regulating effect on the average length of the polyamide chains, so that products with a controlled average molecular weight are obtained, such as she z. B. for the production of fibers are desired.
Die oben bezeichneten Verbindungen, die den Polyamiden erindungsgemäß zuzusetzen sind, sind leicht in bekannter Weise erhältlich z. B. durch Umsetzung von Phenolen mit halogenhaltigen Aldehyden oder von halogenhaltigen Phenolen mit Aldehyden oder von halogenhaltigen Phenolen mit halogenhaltigen Aldehyden und schließlich durch Halogenieren von Di- (oxyphenyl)-methanen. The above-mentioned compounds which are the polyamides according to the invention are to be added, are easily available in a known manner, for. B. through implementation of phenols with halogen-containing aldehydes or of halogen-containing phenols with Aldehydes or of halogen-containing phenols with halogen-containing aldehydes and finally by halogenating di (oxyphenyl) methanes.
Im einzelnen seien genannt : z. B. das Kondensationsprodukt aus a Mol Phenol mit i Mol Chloral (Schmelzpunkt 210 bis 212°), das Kondensations- produkt aus 2 Mol 2, 4-Dichlorphenol mit I Mol Formaldehyd (Schmelzpunkt 165 bis 166°), das Kondensationsprodukt aus 2 Mol 2, 3-Dichlorphenol mit i Mol Chloral (Schmelzpunkt 183 bis 185°), das Kondensationsprodukt aus 2 Mol 2, 4-Dichlorphenol mit i Mol Chloral (Schmelzpunkt 176 bis I78°), das Kondensationsprodukt aus 2 Mol o-Chlorphenol mit i Mol Chloral (Schmelzpunkt 67 bis 69°), das Kondensationsprodukt aus 2 Mol m-Chlorphenol mit i Mol Chloral (Schmelzpunkt 168°), das Kondensationsprodukt aus 2 Mol p-Chlorphenol mit i Mol Chloral l (Schmelzpunkt I47°), chloriertes Di- (p-oxyphenyl)-dimethylmethan mit 3 Cl-Atomen (Schmelzpunkt 78 bis 81°), chloriertes Di-(p-oxyphenyl)-dimethylmethan mit 4 Cl-Atomen (Schmelzpunkt 133 bis 133°), chloriertes Di- (p-oxyphenyl)-dimethylmethan mit io Cl-Atomen (Schmelzpunkt 158 bis 16o°), Di- (2-oxy-5-chlorphenyl)-methan (Schmelzpunkt 171 bis 173°) undDi- (4-oxy-3, 5-dibrom-phenyl)-dimethyhnethan (Schmelzpunkt 166°). The following are mentioned in detail: z. B. the condensation product from a Mole of phenol with 1 mole of chloral (melting point 210 to 212 °), the condensation product from 2 moles of 2,4-dichlorophenol with 1 mole of formaldehyde (melting point 165 to 166 °), the condensation product of 2 moles of 2,3-dichlorophenol with 1 mole of chloral (melting point 183 to 185 °), the condensation product of 2 moles of 2,4-dichlorophenol with 1 mole of chloral (Melting point 176-178 °), the condensation product of 2 moles of o-chlorophenol with 1 mole of chloral (melting point 67 to 69 °), the condensation product of 2 moles of m-chlorophenol with 1 mole of chloral (melting point 168 °), the condensation product of 2 moles of p-chlorophenol with 1 mole of chloral l (melting point 147 °), chlorinated di (p-oxyphenyl) dimethyl methane with 3 Cl atoms (melting point 78 to 81 °), chlorinated di (p-oxyphenyl) dimethyl methane with 4 Cl atoms (melting point 133 to 133 °), chlorinated di (p-oxyphenyl) dimethyl methane with 10 Cl atoms (melting point 158 to 160 °), di- (2-oxy-5-chlorophenyl) methane (melting point 171 to 173 °) and di (4-oxy-3, 5-dibromophenyl) -dimethylethane (melting point 166 °).
Gegebenenfalls können den erfindungsgemäß behandelten Polyamiden in an sich bekannter Weise Pigmente, Farbstoffe, Fiillmittel, Weichmacher oder andere Kunst-oder Naturharze zugesetzt werden. The polyamides treated according to the invention can optionally be used pigments, dyes, fillers, plasticizers or others in a manner known per se Synthetic or natural resins are added.
Beispiel i Schnitzel aus Polyaminocapronsäure werden mit o, 2 °/o des Kondensationsproduktes aus 2 Mol m-Chlorphenol mit i Mol Chloral gut vermischt, wobei die Stücke nicht miteinander verbacken oder verkleben und eine weitere Verarbeitung daher leicht auszuführen ist. Danach wird das Gemisch in einer beheizten Schneckenpresse zu einem Draht verformt und dieser anschließend zerkleinert. Das Molekulargewicht hat sich praktisch nicht verandert. Die relative Viskosität einer 0,5%igen Lösung in m-Kresol bei 25° beträgt vor dem Zusatz des Kondensationsproduktes 1,93 und nach dem Zusatz des Kondensationsproduktes z, 9I. Example i Schnitzel from polyaminocaproic acid are 0.2% the condensation product of 2 moles of m-chlorophenol mixed well with 1 mole of chloral, whereby the pieces are not baked or glued together and further processing therefore easy to do. The mixture is then placed in a heated screw press deformed into a wire and then crushed. The molecular weight has practically not changed. The relative viscosity one 0.5% solution in m-cresol at 25 ° before the addition of the condensation product 1.93 and after the addition of the condensation product z, 9I.
Die Drahtstückchen werden alsdann geschmolzen. The pieces of wire are then melted.
Durch diese Schmelze wird ein mit einem Polyäthylenmantel versehenes
Metallkabel hindurchgezogen. Durch den Zusatz des Kondensationsproduktes wird die
Schmelzviskosität der Schmelze günstig beeinflußt, wodurch die Ummantelung des Kabels
leicht bewerkstelligt werden kann. Die Prülung des nunmehr mit einem Außenmantel
aus dem erfindungsgemäß hergestellten Polyamid versehenen Kabels ergibt nach einer
Lagerung von 96 Stunden bei 70° in einer Sauerstoffatmosphäre, von 24 Stunden an
der Luft bei Raumtemperatur und schließlich von 24 Stunden an der Luft bei -40°
folgendes Vergleichsbild gegenüber einem ebenso behandelten Kabel mit einem mit
bisher bekannten Mitteln stabilisierten Außenmantel :
Danach werden die Schnitzel 24 Stunden bei 70° getrocknet. Ein Teil
der Schnitzel wird 24 Stunden bei 130° unter Überleiten von Luft getempert. Dann
wird je eine o, 5%ige Lösung in m-Kresol hergestellt und die relative Viskosität
dieser Lösungen bei 25° ermittelt.
