摘要
对以异丁烯、异戊二烯、二乙烯基苯为单体，以ＡｌＣｌ３、Ｈ２Ｏ为引发体系，在ＣＨ２Ｃｌ２溶剂中合成三元共聚丁基橡胶的机理进行了研究，考察了Ｈ２Ｏ和ＡｌＣｌ３用量对分子量的影响。实验结果表明Ｈ２Ｏ在该引发体系中为主引发剂。
A polymerization mechanism of butyl terpolymers in CH 2Cl 2 diluent by AlCl 3/H 2O initiating system was investigated. The butyl terpolymer is composed of three monomers, namely: isobutylene,isoprene and divinylbenzene.The effects of H 2O and AlCl 3 on polymerization by classic technology-slurry process was carried out.The result shows H 2O here plays a main initiator role,while AlCl 3 is coinitiator.
