摘要

Title: A PROCESS FOR MAKING A POLYMER OF ACRYLONI TRILE, METHACRYLONITRILE AND OLEFINICALLY UNSATURATED MONOMERS A process for making a thermally stable melt processable acrylonitrile/methacrylonitrile/olefinically unsaturated multipolymer, comprising polymerizing a mixture of acrylonitrile monomer, methacrylonitrile monomer, and olefinically unsaturated monomer in which the rate of addition of the multimonomer mixture isset by the rate of polymerization so that the concentration of unreacted acrylonitrile monomer, unreacted methacrylonitrile monomer and unreacted olefinically unsaturated monomer is low and the polymerization process is in a monomer starved condition.
