摘　　要：采用气-固相法对反式-1,4-聚异戊二烯(TPI)进行氯化改性,制得氯化反式-1,4-聚异戊二烯(CTPI)。主要探讨了氯含量对反式-1,4-聚异戊二烯结晶度的影响,以及氯化后TPI结构的变化。分析结果表明,随着氯含量的升高,CTPI的结晶度下降,熔点降低。随TPI粒径尺寸减小以及其相对分子质量分布变窄,氯化则越容易,氯化程度越均匀,结晶度降低越多。结构表征发现,CTPI分子链结构包括碳-碳双键氯加成、侧甲基氯取代、环氧基团等。Chlorinated trans-1, 4-polyisoprene （CTPI） was prepared though chlorination modification trans-1,4-polyisoprene（TPI）by gas-solid phase. The effect of chlorine content on the crystallinity of TPI was mainly discussed. Analytic results indicate that the crystalline content and melting point decrease as the chlorine content of CTPI increases. With the de- crease of particle size of TPI and the narrowing of its molecular weight distribution , it is easy to chloridize. The more homogeneous chlorinated degree of CTPI is,the lower its degree of crystallization becomes. The characterization results show that the molecular chain structure of CTPI includes C = C double bond by addition of chlorine, chlorine-substituted methyl side, epoxide group etc.
