    Patent number: 5679741
    Abstract: Use of a polymer blend based on a polymerizate of groups of tetrafluoroethylene derivatives as a processing aid for polyvinyl chloride resins, chlorinated polyvinyl chloride resins, polyolefins and styrene-based resins.Use of a polymer blend as a processing aid for polyvinyl chloride resins, chlorinated polyvinyl chloride resins, polyolefins and styrene-based resins and their mixtures, the polymer blend comprising particles of tetrafluoroethylene polymerizate, these particles being totally or partially encapsulated by a styrene-acrylonitrile copolymer, the amount of the said blend used being such that the tetrafluoroethylane polymerizate represents between 0.05 parts by weight and 20 parts by weight per 100 parts by weight of resins and/or polymers processed.
