【摘要】 本工作采用引发-转移（inifer）技术对氯化丁基橡胶（CIIR）与a-甲基苯乙烯（a-MeSt）进行接枝共聚。在该反应中CIIR既是大分子引发剂又是接枝物主链,而AlEt₂Cl则是共引发剂,两者组成了inifer体系。采用IR、GPC、¹H-NMR法对产物进行了表征,证明接枝共聚物为CIIR-g-Pa-Mest 结构。更多还原

【Abstract】 The graft copolymer of chlorinated butyl rubber and poly ( α-methyl styrene )[CIIR-g-P ( α-MeSt )] was synthesized by using new " inifer " technique, in which CIIR was both a backbone of the grafted copolymer and macromolecular initiator, and AlEt2Cl was the component as a coinitiator. α-MeSt was " grafted from " the mixed solvent of CH2Cl2/hexane . The ultimate product was characterized by means of IR, GPC and1H-NMR, and the grafted structure of CIIR-g-P ( α-MeSt ) was confirmed.更多还原
