The present invention provides a novel solvent which is capable of providing an excellent isobutylene polymer, little affects the environment, has a lower solubility in water than those of halogenated hydrocarbons having 1 or 2 carbon atoms and can be decomposed relatively easily.
Namely, the present invention relates to: a process for producing an isobutylene polymer, which comprises performing a cationic polymerization reaction in a solvent containing primary and/or secondary monohalogenated hydrocarbon(s) having 3 to 8 carbon atoms, and an isobutylene polymer thus obtained; and a process for producing an isobutylene polymer having a vinyl group introduced into the terminal thereof, which comprises reacting the isobutylene polymer produced above with 1,9-decadiene or allyltrimethylsialne, and an isobutylene polymer thus obtained.
本发明提供了一种新型溶剂,它能够提供优良的异丁烯聚合物,对环境影响小,在水中的溶解度低于具有 1 或 2 个碳原子的卤代烃,并且相对容易分解。
也就是说,本发明涉及:一种异丁烯聚合物的生产工艺,包括在含有具有 3 至 8 个碳原子的一级和/或二级单卤代烃的溶剂中进行阳离子聚合反应,以及由此获得的异丁烯聚合物;以及一种在其末端引入乙烯基的异丁烯聚合物的生产工艺,包括将上述生产的异丁烯聚合物与 1,9-癸二烯或烯丙基三甲基炔反应,以及由此获得的异丁烯聚合物。
