Abstract
The present invention relates to molding materials and sheets which possess improved aging and contact properties, and which comprise a plastic blend based on an acrylate-grafted vinyl chloride polymer, preferably polyvinyl chloride, having an acrylate content of 30-60% by weight, preferably 35-50% by weight, based on 100 parts by weight of vinyl chloride polymer. The molding materials and sheets further comprise another polymer or polymer blend having a glass transition temperature greater than 30.degree. C., preferably greater than 40.degree. C., which is compatible with the vinyl chloride graft polymer. If necessary, additional fillers, processing agents and other conventional additives may be included, so long as 28-44.9% by weight, preferably 30-44.8% by weight, of the vinyl chloride polymer grafted with acrylate is present and 55.1-72% by weight, preferably 55.2-70% by weight, of the other polymer or polymer blend is present.
