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 1>halo; R 1>1-6C alkyl; R 2>CR 3>R 4>-CY 1>R 5>R 6>; R 3>-R 6>H, 1-10C alkyl or aryl; R 7>H, 1-4C alkyl or phenyl; R 8>1-6C alkyl; R 9>, R 10>H 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.
