STUDY ON GRAFT POLYMERIZATION OF STYRENE ONTO PREITTADIATED POLYCHLOROTRIFLUOROETHYLENE FILMS
预辐照聚三氟氯乙烯薄膜接枝苯乙烯的研究

In this paper, we reported that peroxy fluorine containing radicals were slowly decayed, and existed for a long time at room temper ture. The effective period of preir-radiation was over 6 years. Influences of temperature, inorganic additives and organic-solvents on styrene graft reaction has been investigation. The percentage of grafting increased with the lowering of he reaction temperature, and the homoplymerization of styrene can be effectively inhilited by adding ferric chloride in styrene during the graft reaction. The structural characteristics of polychlorotrifluoroethylene-styrene copolymer were also studied.
