用~(60)Co-γ射线共辐照法作了聚氟乙烯薄膜-苯乙烯的辐射接枝共聚合反应,研究了单体浓度、辐照剂量率、温度及薄膜厚度与接枝共聚反应速度的关系。在实验条件下,接枝共聚反应速度分别与单体浓度、辐照剂量率及薄膜厚度的2.5、0和-1次方相关联。接枝共聚反应的总活化能为141 8kJ/mol。 Radiation graft copolymerization of polyvinyl fluoride film and styrene was carried out by co-irradiation with ~ (60) Co-γ ray. The effects of monomer concentration, irradiation dose rate, temperature and film thickness on the graft copolymerization The speed of the relationship. Under the experimental conditions, the rate of graft copolymerization was correlated with the monomer concentration, radiation dose rate and the 2.5,0 and -1 power of the film thickness respectively. The total activation energy of the graft copolymerization was 141 8kJ / mol.
