  • Method for forming highly reactive olefin functional polymers
    Patent number: 10174138
    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 C4 feed containing iso-butene and other C4 olefins 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.
