摘要

Preparing isobutene polymer comprises polymerizing isobutene or isobutene containing monomeric mixture in the presence of Lewis acid, initiators and at least compound (A) from a metal containing compound; orthocarbonic acid ester (c) and/or an epoxy compound (d). Preparing isobutene polymer comprises polymerizing isobutene or isobutene containing monomeric mixture in the presence of Lewis acid, initiators and at least compound (A) from a metal containing compound of formula (MZ m(OR 1) n) (a), (MZ o(OR 2) p) (b) or (MZ q(OR 1) r) (a1); orthocarbonic acid ester of formula (R 7-C(OR 8) 3) (c) and/or an epoxy compound of formula (d). M : metal or metalloid, preferably B, Al, Si, Sn(IV), Ti(IV), V or Fe(III); Z, Y 1halo; R 11-6C alkyl; R 2CR 3R 4-CY 1R 5R 6; R 3-R 6H, 1-10C alkyl or aryl; R 7H, 1-4C alkyl or phenyl; R 81-6C alkyl; R 9, R 10H or 1-10C alkyl; m, o : 0-4; n, p : 1-5; and either q, r : 0-4; or q+r : an oxidation number of M. Where: the sum of m and n corresponds to the oxidation number of M. Independent claims are included for: (1) an isobutene polymer obtained by the process; and (2) a process for functionalizing the isobutene-polymer by hydrosilylation-, hydrosulfonation-, electrophilic aromatic substitution-, epoxidation- process and optionally reacting with a nucleophile, or hydroboration and optionally oxidative separation process, or converting with an enophile in an En-reaction, or addition of halo and halo-hydro compound, or hydroformylation and optionally hydrogenation process, or reductive amination process, or copolymerization with an olefinic unsaturated dicarboxylic acid or its derivative, or amination of nucleophilic substitution.
