摘要
近年来,Turro等人发现,外磁场能提高一些由油溶性酮类化合物(如二苄基酮)为引发剂的乳液聚合体系的分子量,并且显著地影响所生成聚合物的立体构型,因而引起了人们的注意。
The bulk polymerization of styrene initiated by AIBN which was sensitized by PVN could, be effected by magnetic field under irradiation with 320 nm monochromic light. The molecular weight distribution of polystyrene is dependent on the concentration and molecular weight of PVN. It was confirmed by experiments that the critical molecular weight and concentration of PVN which effected on the polymerization are 1.7×103 and 1.62×10-3 mol/l respectively. The cause which is responsible for these phenomena was discussed qualitatively.
