| 摘 要： | <正> 由于苯乙烯(St)和丙烯腈(AN)竞聚率的差异,在乳液共聚中所得产物为组成不均匀的共聚物,因此一般在反应后期通过复杂计算和实验验证补加消耗快的单体,或采用回收大量单体等方法得到组成均匀的共聚物。St-AN乳液共聚物的分子量较大,产物不

| Abstract: | a-methyl styrene dimer was used as a regulator in the copolymerization of styrene and aerylonitrile. When a-methyl styrene dimer and the monomers were added dropwi-se into the system of emulsion copolymerization, very few monomer droplets were observed. Under this condition, the reaction was stable and a satisfactory method in controlling M. W. and the homogeniety of the copolymer composition was obtained. |
