Description

Verfahren zur Herstellung von Kunststoffen Es ist bekannt, daß sich Vinylester mit ungesättigten Chlorkohlenwasserstoffen unter Bildung von Mischpolymerisaten zusammenpolymerisieren lassen. Wir haben nun die überraschende Tatsache gefunden, daß man neuartige Polyvinylverbindungen herstellen kann, wenn man organische Vinylester in Gegenwart geringer oder größerer Mengen gesättigter Chlorkohlenwasserstoffe bis zu einer noch nicht festen, vorzugsweise zähflüssigen Konsistenz des Polymerisats polymerisiert. Die Polymerisation erfolgt nach den üblichen Methoden. Die neuen Körper sind technisch auf allen Gebieten der Verwendbarkeit der normalen Polyvinylester brauchbar, deren Umfang sie durch ihre besonderen Eigenschaften erweitern. Sie sind insbesondere auch gute Klebmittel und vor allem auch als `'Teichmacher geeignet.Process for the production of plastics It is known that Vinyl esters with unsaturated chlorinated hydrocarbons with the formation of copolymers let polymerize together. We have now found the surprising fact that new types of polyvinyl compounds can be produced by using organic vinyl esters in the presence of small or large amounts of saturated chlorinated hydrocarbons up to to a not yet solid, preferably viscous consistency of the polymer polymerized. The polymerization takes place according to the usual methods. The new Bodies are technical in all areas of usability of normal polyvinyl esters useful, the scope of which they expand through their special properties. they are especially good adhesives and above all also suitable as a pond maker.

Beispiel i 86 g Vinylacetat wurden in Mischung mit 86 g Tetrachlorkohlenstoff unter Verwendung von i g Benzoylsuperoxyd durch il/2stündiges Erhitzen am Rückflußkühler polymerisiert. Es entstand eine zähflüssige, durchsichtige Lösung. Nach Entfernung der überschüssigen Monomeren bei ioo° und io mm wurden 9o g Reaktionsprodukt als goldgelbe, viskose Flüssigkeit erhalten. Die Elementarzusammensetzung der Polymerisate war folgende 37,5 % C; 4,3 °/o H; 35,2 % Cl. Beispiel 2 86 g Vinylacetat wurden in Mischung mit 154 g Tetrachlorkohlenstoff unter Verwendung von z g Benzoylsuperoxyd durch 33/4stündiges Erhitzen am Rückflußkühler polymerisiert. Die Aufarbeitung erfolgte wie im Beispiel r und lieferte z2o g einer farblosen zähen Flüssigkeit von folgender Elementarzusammensetzung 34,811/0 C; 3,90/0 H, 40,4% Cl.EXAMPLE I 86 g of vinyl acetate were polymerized in a mixture with 86 g of carbon tetrachloride using ig benzoyl peroxide by refluxing for 1/2 hour. A viscous, transparent solution was created. After removing the excess monomers at 100 ° and 100 mm, 90 g of reaction product were obtained as a golden yellow, viscous liquid. The elemental composition of the polymers was 37.5% C; 4.3% H; 35.2 % Cl. EXAMPLE 2 86 g of vinyl acetate were polymerized in a mixture with 154 g of carbon tetrachloride using zg benzoyl peroxide by refluxing for 33/4 hours. The work-up was carried out as in Example r and yielded 20 g of a colorless viscous liquid with the following elemental composition: 34.811 / 0 C; 3.90 / 0 H, 40.4% Cl.

Die Produkte haben eine gute Löslichkeit in Aceton, Alkoholen, Äther, Benzol, Estern, Chlorkohlenwasserstoffen, Pyridin. Die relativ geringe Viskosität selbst hochkonzentrierter Lösungen begünstigt ihre Verwendbarkeit in der Lackindustrie. Beispiel 3 86 g Vinylacetat wurden in Mischung mit zog g Pentachloräthan unter Verwendung von 0,5 g Benzoylsuperoxyd erwärmt. Es trat eine kurze, sehr heftige Reaktion ein. Das Reaktionsprodukt wurde im Vakuum bei zoo° von überschüssigen Monomeren befreit. Die farblose, zähflüssige Verbindung hatte folgende Elementarzusammensetzung: 3z,5 % C; 3,4 0/0 H: 48,o 0/0 Cl. Beispiel 4 86 g Vinylacetat wurden mit 537 g Chloroform gemischt, mit 2,6 g Benzoylsuperoxyd versetzt und erhitzt. Nach rostündigem Kochen am Rückflußkühler wurde das überschüssige Vinylacetat und Chloroform mit Wasserdampf abgetrieben. Das pastenartige Endprodukt hatte eine Verseifungszahl von 538 und einen Chlorgehalt von 14,9 0/0.The products have good solubility in acetone, alcohols, ethers, benzene, esters, chlorinated hydrocarbons, pyridine. The relatively low viscosity of even highly concentrated solutions makes them easy to use in the paint industry. Example 3 86 g of vinyl acetate were heated in a mixture with drawn g of pentachloroethane using 0.5 g of benzoyl peroxide. There was a brief, very violent reaction. The reaction product was freed from excess monomers in vacuo at zoo °. The colorless, viscous compound had the following elemental composition: 3z, 5% C; 3.4 0/0 H: 48.0 0/0 Cl. Example 4 86 g of vinyl acetate were mixed with 537 g of chloroform, 2.6 g of benzoyl peroxide were added and the mixture was heated. After boiling for rusting hours on the reflux condenser, the excess vinyl acetate and chloroform were driven off with steam. The paste-like end product had a saponification number of 538 and a chlorine content of 14.9%.
