    摘要： Improvements in polyvinyl fluoride obtained by adding iodine or an iodine compound to the vinyl fluoride monomer prior to or during polymerization thereof and for adding iodine or an iodine compound to polyvinyl fluoride. The polymerization is preferably in the aqueous phase above the critical temperature in the presence of azo-bis-isobutyramidine hydrochloride and N-alkyl substituted such compounds as catalyst. The iodine content of the polymer, calculated as iodine, is preferably 0.001 to 1 weight percent based upon vinyl fluoride content.
