Description
Stabilisieren von chlorhaltigen Vinylpolymerisaten Es ist bekannt, chlorhaltige Vinylpolymerisate, insbesondere Polyvinylchlorid, mit organischen Barium-Cadmium-Salzen, insbesondere fettsauren Salzen, gegen Zersetzung durch Wärme und Licht zu stabilisieren. Der Zusatz dieser Substanzen verhindert die Verfärbung der Produkte während der Verarbeitung und beim späteren Gebrauch der Bertigartikel.Stabilizing chlorine-containing vinyl polymers It is known chlorine-containing vinyl polymers, in particular polyvinyl chloride, with organic barium-cadmium salts, especially fatty acid salts, to stabilize against decomposition by heat and light. The addition of these substances prevents discoloration of the products during the Processing and later use of the Bertartikel.
Es wurde nun gefunden, daß die Stabilisierwirkung solcher organischer Barium-Cadmium-Salze wesentlich verbessert werden kann, wenn diese Stabilisatoren im Gemisch mit mischsalzartigen Verbindungen aus Bisphenolen, Carbonsäuren und zwei- oder mehrwertigen Metallen verwendet werden. It has now been found that the stabilizing effect of such organic Barium cadmium salts can be improved significantly if these stabilizers in a mixture with mixed salt-like compounds of bisphenols, carboxylic acids and di- or polyvalent metals are used.
Als Carbonsäuren, die mit den Bisphenolen die mischsalzartigen Verbindungen bilden, eignen sich in erster Linie aliphatische oder aromatische Säuren mit 2 bis 20 C-Atomen, und zwar vorzugsweise Stearin- und Laurinsäure. Es sind aber auch substituierte Benzoesäuren, vorzugsweisep-tert.-Butylbenzoesäure, als zu verwendende Carbonsäuren gut geeignet. As carboxylic acids, the mixed salt-like compounds with the bisphenols form, are primarily aliphatic or aromatic acids with 2 to 20 carbon atoms, preferably stearic and lauric acid. But there are also substituted ones Benzoic acids, preferably p-tert-butylbenzoic acid, as the carboxylic acids to be used well suited.
Als Bisphenol wird zweckmäßigerweise die als Bisphenol A bekannte Verbindung, nämlich das 2,2-Bis-(-4-oxy-phenyl)-propan, verwendet. Um ein Mischsalz bilden zu können, muß das Metallatom mehrwertig sein; vorzugsweise hat sich Zink bewährt, aber auch Barium, Cadmium und Calcium sind gut geeignet. The bisphenol known as bisphenol A is expediently used Compound, namely the 2,2-bis (- 4-oxy-phenyl) -propane, used. To a mixed salt To be able to form, the metal atom must be polyvalent; preferably has zinc proven, but barium, cadmium and calcium are also suitable.
Die mischsalzartige Verbindung wird im allgemeinen in einer Menge von 0,1 bis 25 Gewichtsprozent, vorzugsweise 3 bis 10 Gewichtsprozent, dem organischen Barium-Cadmium-Salz, vorzugsweise Barium-Cadmium-Laurat, zugesetzt und in Mischung mit diesem als Stabilisator verwendet. Die Dosierung im Polymerisat beträgt 0,1 bis 5 Gewichtsprozent, vorzugsweise 2 bis 3 Gewichtsprozent. Das erfindungsgemäß zu verwendende Stabilisatorgemisch wird zweckmäßigerweise als Mischung seiner Komponenten verwendet, jedoch können diese auch einzeln den zu stabilisierenden Polymerisaten zugesetzt werden. The mixed salt-like compound is generally used in an amount from 0.1 to 25 percent by weight, preferably 3 to 10 percent by weight, of the organic Barium cadmium salt, preferably barium cadmium laurate, added and mixed used with this as a stabilizer. The dosage in the polymer is 0.1 up to 5 percent by weight, preferably 2 to 3 percent by weight. That according to the invention The stabilizer mixture to be used is expediently as a mixture of its components used, however, these can also be added individually to the polymers to be stabilized will.
Die Wirksamkeit des erfindungsgemäß zu verwendenden Stabilisatorgemisches kann noch dadurch verbessert werden, daß dem Polymerisat zusätzlich Anteile von Epoxydverbindungen oder Organophosphiten beigegeben werden. Diese Substanzen werden zweckmäßigerweise in gleicher Menge zugegeben wie der Barium-Cadmium-Stabilisator, was an sich für Barium-Cadmium-Stabilisatoren bereits bekannt ist. The effectiveness of the stabilizer mixture to be used according to the invention can be further improved by adding proportions of Epoxy compounds or organophosphites are added. These substances will expediently added in the same amount as the barium-cadmium stabilizer, which is already known for barium-cadmium stabilizers.
