摘　　要：采用水相悬浮法氯化高等规度聚丁烯-1（iPB）。在相同氯化条件下,熔体流动指数（MFR）35的iPB的氯化产品氯含量高于熔体流动指数1.6的产品;采用30-50℃两阶段升温的方法,可以在5 h内获得氯含量高于50%（质量分数）的产品;钠盐的存在会抑制iPB的氯化;随着氯含量的增加,氯化高等规度聚丁烯-1在甲苯中的溶解度增加,当氯含量达到60%时,几乎100%溶解。The aqueous suspension method was used in the modification of polybutene-1 through chlorination. At the same chlorination conditions, chlorinity of chlorinated highly isotactic polybutene-1 with MFR 35 was higher than that of MFR 1.6. While using two-step raising temperature method in 30-50 ℃ ,product with chlorinity exceeded 50 wt% was obtained within 5 h. It was also found that sodium salt can restrain chlorination reaction. When chlorinty increased, the solubility of chlorinated isotactic polybutene-1 became larger in toluene solution. The chlorinated isotactic polybutene-1 nearly absolutely dissolves in toluene when chlorinity reached 60 %.
