摘要： 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 C 4 feed containing iso-butene and other C 4 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.

摘要： A process for the preparation of polybutene having an exo-olefin content of at least 50 mol. % from an isobutene or an isobutene-containing monomer feedstock, which process comprises contacting said isobutene or isobutene-containing feedstock, with a Lewis acid catalyst complexed with a Lewis base, in a substantially or completely apolar polymerization medium, and initiating polymerization of said isobutene or isobutene-containing feedstock with an initiator. The Lewis acid catalyst is a Lewis acid of the formula R'AlCl 2 , wherein R' is a hydrocarbyl group; the Lewis base is a dihydrocarbyl ether wherein each hydrocarbyl group is independently selected from hydrocarbyl groups having 1 to 8 carbon atoms and one or both hydrocarbyl groups of the dihydrocarbyl ether are substituted with an electron withdrawing group; and the initiator is a compound of the formula RX, wherein X is a halide; R is a hydrocarbyl group capable of forming a stable carbocation, and the carbon linking group R to group X is tertiary, benzylic or allylic. The catalyst complex is pre-activated by addition of water, and the pre-activated catalyst complex is subsequently reacted with from about 0.1 to about 2 molar equivalents, per equivalent of Lewis acid, of a trialkyl aluminum compound wherein each alkyl group of the trialkyl aluminum compound has at least 2 carbon atoms.
