Description
Es ist bekannt, schlagfestes Polyvinylchlorid durch Mischen mit Kautschuk oder kautschukartigen Mischpolymerisaten, z.B. von Polymerisaten aus Butadien-Acrylnitril oder Butadien-Styrol, oder ähnlichen Mischpolymeren herzustellen. Die Verwendung dieser noch Doppelbindungen enthaltenden Komponenten ergibt jedoch Produkte, die nicht alterungsbeständig sind und außerdem geringe Wärmebeständigkeit zeigen. Man hat auch schon vorge-It is known to make high-impact polyvinyl chloride by mixing with rubber or rubber-like Copolymers, e.g. of polymers made of butadiene-acrylonitrile or butadiene-styrene, or the like To produce mixed polymers. The use of these still containing double bonds Components, however, results in products that are not resistant to aging and also have poor heat resistance demonstrate. One has already planned

These known methods of notched impact strength and good water resistance have the disadvantage that the polymers are at high speed. A further advantage of the products obtained is the temperatures incorporated on the mixing roll, their flame retardancy and their transparency, and because of the long rolling time, they also have the advantage that they are resistant to aging due to the high temperatures that arise in the process. The polymers can be mixed directly. It is also known that injection molded parts can be processed. Mixtures of polyvinyl chloride and the above can of course also be produced by plasticizers, fillers, dyes or pigment polymers by mixing and incorporating the separate elements, depending on the desired use, before the polymer emulsions produced. Stabilizers together fails. This process can also be incorporated, but it is part of the fact that the products obtained have poor water resistance over normal polyvinyl chloride due to the high improved thermal stability of the polymers against emulsifier content,

Die Mengen, in denen die schäften: chlorierten Äthylen-Propylen-Mischpolymerisate eingesetzt werden, liegen im Bereich zwischen 5 bis 30 Gewichtsprozent, bezogen auf die Summe der polymerisierbaren Verbindungen. Neben Vinylchlorid werden zusätzlich Emulsionen von PoIyacrylsäureestern, wie Polyacrylsäurebutylester, PoIyacrylsäureoctylester oder Polyacrylsäuretridecylester, eingesetzt. Diese Verbindungen werden in Mengen von 1 bis 30 Gewichtsprozent, vorzugsweise von 1 bis 10 Gewichtsprozent, bezogen auf das eingesetzte monomere Vinylchlorid, verwendet. Die Polymerisation wird unter Verwendung bekannter Schutzkolloide oder Pigmente, z.B. Gelatine, Polyvinylalkohol oder Bariumsulfat, durchgeführt. Als Katalysatoren eignen sich radikalbildende Katalysatoren, wie Benzoylperoxyd, Di-tert.-butylperoxyd oder Azodiisobuttersäurenitril. Gegebenenfalls können dem Polymerisationsansatz geringe Mengen eines Emulgators, wie Alkyl- oder Arylsulfonate, zugesetzt werden.

The quantities in which the shafts: chlorinated ethylene-propylene copolymers are used, are in the range between 5 and 30 percent by weight, based on the sum of the polymerizable compounds. In addition to vinyl chloride are also emulsions of polyacrylic acid esters, such as butyl polyacrylate, octyl polyacrylate or tridecyl polyacrylate, used. These compounds are used in amounts of 1 to 30 percent by weight, preferably from 1 up to 10 percent by weight, based on the monomeric vinyl chloride used. The polymerization is made using known protective colloids or pigments, e.g. gelatin, polyvinyl alcohol or barium sulfate. Suitable catalysts are radical-forming catalysts, such as benzoyl peroxide, di-tert-butyl peroxide or azodiisobutyronitrile. If necessary, the Small amounts of an emulsifier, such as alkyl or aryl sulfonates, can be added to the polymerization batch. The amount of emulsifier is then at most 0.2 percent by weight, based on the polymerizable Links. The chlorinated ethylene-propylene copolymers are generally
