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.
