PROCESS FOR THE POLYMERIZATION OF ORGANIC COMPOUNDS ETHYLENICALLY UNSATURATED

摘要

Vinylidene chloride polymers and copolymers are prepared by contacting vinylidene chloride monomer alone or in mixture with other ethylenically unsaturated monomers with a catalytic system consisting of an organic per-compound, an organic compound of zirconium or cobalt and an acid compound according to the definition of Br?nsted and Lowry in an organic solvent medium. High yields and polymerization speeds are achieved at low polymerization temperatures (10-35.degree.C).
