IMPROVED EMULSION POLYMERIZATION OF VINYLIDENE FLUORIDE POLYMERS

摘要

Vinylidene fluoride polymers having a wide range of molecular weights are produced with reduced initiator consumption by using trichlorofluoromethane as a chain transfer agent in the emulsion polymerization process. Vinylidene fluoride homopolymers made by the process have a significantly reduced tendency to generate cavities at high temperatures and a greater resistance to discoloration at high temperatures.
