Abstract

High molecular weight vinyl fluoride or vinylidene fluoride polymers are obtained by polymerizing at the autogenous pressure of the polymerization mixture, at a temperature between 50 DEG and 150 DEG C. in the presence of an organic peroxide as catalyst and in the presence of a saturated fluorinated or fluorochlorinated hydrocarbon or mixture of two or more such hydrocarbons which is capable of dissolving the monomer and the catalyst and which has a boiling point above room temperature. Preferably the polymerization is carried out in the presence of fluoro trichloromethane or trifluorotrichloroethane. Conventional peroxide catalysts are used.
