Title:
高反応性オレフィン機能性ポリマーを形成するための方法
Document Type and Number:
Japanese Patent JP6594572
Kind Code:
B2
Abstract:
An improved process for the preparation of polybutene having an exo-olefin content of at least 50 mol. % by the polymerization of iso-butene, or a Cfeed containing iso-butene and other Colefins using (i) a Lewis acid•Lewis base catalyst complex and an alkyl halide initiator, in a substantially or completely apolar polymerization medium, in the presence of a hindered alcohol or alkoxyaluminum dichloride. In the above polymerization reaction, it has been found that a hindered alcohol or hindered alkoxyaluminum dichloride will function as an "exo enhancer" resulting in high isobutene conversion and the production of a polybutene product having a high terminal vinylidene content, while maintaining a target molecular weight.
