摘要
借助 Ｄ Ｓ Ｃ， Ｉ Ｒ，１ Ｈ－ Ｎ Ｍ Ｒ 方法对搅拌式固相氯化制备的氯化等规聚丙烯（ Ｃ Ｉ Ｐ Ｐ） 的宏观氯原子分布和微观氯原子分布进行了分析。结果表明，搅拌式固相氯化法能够迅速破坏等规聚丙烯的结晶，从而得到宏观氯原子分布均匀的 Ｃ Ｉ Ｐ Ｐ， 此方法制备的 Ｃ Ｉ Ｐ Ｐ 主要为等规聚丙烯分子链上的仲氢原子被取代的产物。
The structure of chlorinated isotactic polypropylene(CIPP) was analyzed by DSC,IR,and 1H-NMR.The results showed that the remaining crystallinity of CIPP disappeared completely when the degree of chlorination surpassed 45% and it would disappear at 40% when the reaction temperature inlater chlorination stage was improved.The structure of CIPP unit mainly existed in the form of —CH(CH3)—CHCl— when the degree of chlorination was lower than 42%.
