Vinyl Polymerization

XII. Ionic Polymerization of Phenyl Vinyl Ether Catalyzed by Boron Fluoride and Stannic Chloride

Abstract

(1) At 40°C, cationic polymerization of phenyl vinyl ether catalyzed by BF3.(C₂H₅) ₂O in benzene was carried out.The initial rate was found to be expressed by the equation: R_O=k [M][C](2) The rate of polymerization of phenyl vinyl ether catalyzed by SnC1₄ in carbon tetrachloride was measured.The rate equation was expressed by the equation.R_O=k [M][C] The activation energy was 5300 cal/mol.The polymer thus produced has about one free phenolic OH group per molecule.As by-product, a considerable amount of free phenol was isolated.
