PROCESS FOR PRODUCTION OF POLYMERS, VINYL CHLORIDE RESIN COMPOSITIONS AND MOLDINGS

摘要

[PROBLEMS] To produce efficiently a polymer having a high molecular weight and a narrow molecular weight distribution. [MEANS FOR SOLVING PROBLEMS] A process for the production of polymers by dropping a vinyl monomer into a medium in the presence of a thermally decomposable polymerization initiator, characterized by satisfying the relationships (1) and (2) during the polymerization: relationship (1): 3 × 10⁴ < W
