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

Can propose polyvinyl chloride with chlorinated poly- io. The polymers show excellent olefinic mixing. 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,
