摘要：
A PROCESS FOR THE CONTINUOUS PRODUCTION OF SOLID POLYVINYLIDENE HALIDE RESINS WHICH COMPRISES THE COPOLYMERISATION OF A MIXTURE OF STARTING MATERIALS SUCH AS VINYLIDENE HALIDES ACRYLONITRILE ACRYLIC ACID, METHACRYLIC ACID ITACONIC ACID AND CATALYST AND EMULSIFIERS TOGETHER WITH A POLYMERISED COMPONENT OF A SOLID POLYVINYLIDENE HALIDE RESIN OBTAINED BY EMULSION POLYMERISATION BY MEANS OF FREEZING COAGULATION.
