    Abstract: A process is disclosed for preparing a polyacrylate-modified polyvinyl chloride processing aid for polyvinyl chloride by sequentially polymerizing the vinyl chloride and the desired acrylate ester monomer. Thus, a conventional vinyl chloride suspension polymerization is conducted at a controlled rate of agitation and in the presence of a specified concentration of suspending agent and is then halted at or near its completion; unreacted vinyl chloride monomer is removed, a minor proportion of an acrylate ester monomer, e.g., methyl methacrylate, which has been pre-mixed with a fresh supply of a free radical initiating catalyst is added and polymerization is resumed and continued until the acrylate ester monomer polymerizes in and/or on the particles of the previously polymerized polyvinyl chloride. The polyacrylate-modified PVC thereby recovered is an effective aid for processing conventional PVC, or it can be processed per se since it is suitable for calendering or extruding.

    Abstract: Interpolymers especially useful as processing aids for polyvinyl chloride (PVC) are prepared by polymerizing vinyl chloride in the presence of polymethacrylonitrile (PMAN) or by polymerizing methacrylonitrile in the presence of polyvinyl chloride. In a preferred method, a conventional PVC polymerization is halted at or near its completion, unreacted monomer is removed, a minor proportion up to about 50 percent of methacrylonitrile (MAN) monomer, based on the weight of the interpolymer, is added and the reaction continued until the MAN polymerizes. The PVC-PMAN interpolymer recovered from such a system is an effective aid in processing conventional PVC, or it can be used per se since it is readily processable by calendering or extruding.
