  • Method of producing mixtures of polyvinyl chloride and polymers based on conjugated dienes and acrylonitrile
    Publication number: 20020068786
    Abstract: The invention relates to a method of producing mixtures of polyvinyl chloride and polymers based on conjugated dienes and acrylonitrile, by mixing powdered polyvinyl chloride with latexes based on conjugated dienes and acrylonitrile and then coagulating the mixture. The method according to the present invention represents an inexpensive and environmentally friendly method of producing the mentioned mixtures, the physical behavior of the resulting mixtures being no different to that of corresponding mixtures produced by the dry blend method or the latex blend method.
