研究了AIBN/NaNO2/FeSO4.7H2O存在下苯乙烯本体聚合行为,发现100℃以上时具有活性聚合特征,AIBN/NaNO2/FeSO4.7H2O配比为1/3/3时分子量多分散性指数控制较好,聚合物分子量多分散性指数在1.1～1.8之间,聚合过程转化率和分子量随时间的增加而增大。
The polymerization behavior of styrene in the presence of AIBN / NaNO2 / FeSO4.7H2O was investigated. It was found that the polymerization of styrene was more than 100 ℃. When the ratio of AIBN / NaNO2 / FeSO4.7H2O was 1/3/3, the molecular weight polydispersity index Good, polymer molecular weight polydispersity index between 1.1 to 1.8, the polymerization process conversion and molecular weight increases with time increases.
