Polymerization of open-chain ethylenically unsaturated monomers, e.g. to isobutene-styrene copolymer for film, sealant, adhesive or stent, uses heterogeneous catalyst of solvated metal cation and weakly or non-coordinating anion on support

摘要

In polymerization of monomers with ethylenically unsaturated groups in open chain structures in the molecule, the polymerization catalyst is a heterogenized metal complex (I) obtained by contacting a homogeneous metal complex (II) with a suitable support material, where (II) has a mono- to hexa-valent solvated metal cation containing a group 3-12 transition metal, lanthanide or group 2 or 13 metal, 1 or more molecules of solvent and optionally charged ligand, and weakly or non-coordinating anion. In polymerization of monomers with ethylenically unsaturated groups in open chain structures in the molecule, the polymerization catalyst is a heterogenized metal complex (I) obtained by contacting a homogeneous metal complex of formula (II) with a suitable support material: [M(L)a(Z)b]m+ m(A-) (II); M : a group 3-12 transition metal, a lanthanide or a group 2 or 13 metal; L : a solvent molecule; Z : a ligand with 1 or more charges; A-a weakly or non-coordinating anion; a : 1 or more; b : 0, 1 or more; a+b : 4-8; m : 1-6. Independent claims are included for the following: (1) heterogenized metal complexes (IA), suitable as polymerization catalysts, obtained by contacting specified homogeneous metal complexes (IIA) with a suitable support material; (2) use of (I) as catalyst in the polymerization of ethylenically unsaturated monomers; (3) highly reactive copolymers of isobutene and vinylaromatic monomer(s) produced by this process.
