Abstract
Improvement in the process of mass preparation of polymers and copolymers based on vinyl chloride by two-stage polymerization, characterized in that it consists in carrying out the prepolymerization operation on a fraction of the monomer (s) used in the reaction in the course of the final polymerization operation, in a prepolymerizer under high speed agitation until a prepolymerized product having a conversion ratio of the monomer (s) of the order of 7 to 15 percent and preferably close to 8 to 10 percent is obtained, and then in carrying out the final polymerization operation on a reaction medium constituted by the prepolymerization and a complementary amount of monomer or comonomers, in one or more polymerizers under slow stirring, however, this agitation speed remaining sufficient to ensure a good thermostatization of the medium reactional until the end of the polime rization.
