Abstract

Random or block co- or terpolymers produced by using metal complex catalysts in a reaction of one conjugated diene monomer with one aromatic Random or block co- or terpolymers produced by using metomers with one aromatic alpha-olefin or terpolymers of one conjugated diene monomer with one aromatic alpha-olefin and one aliphatic alpha-olefin by using metal complexes comprising metals of group 3 to 10 of the Periodic System of the Elements in combination with activators and optionally a support material. More particularly the metal complexes used for the synthesis of co- or terpolymer are lanthanide metals. Even more particularly diene monomer(s) and aromatic alpha-olefin monomer(s) such as, but not limited to, butadiene and styrene or isoprene and styrene are copolymerized giving random or block copolymers or butadiene, styrene and isoprene are terpolymerized giving random or block terpolymers using metal complexes comprising lanthanide metals in combination with activators and optionally a support material. Preferably random co- or terpolymers are formed.

Description

technical field [0001] The present invention relates to random or block copolymers or terpolymers formed by copolymerization or terpolymerization of conjugated diene monomers with aromatic α-olefin monomers and optionally aliphatic α-olefin monomers Metapolymers, more specifically related to the formation of random or block copolymers by the copolymerization of a conjugated diene monomer and an aromatic alpha-olefin monomer, and even more specifically by a The copolymerization reaction of a conjugated diene monomer and an aromatic alpha-olefin monomer forms a random copolymer. Background technique [0002] Metal complex catalysts are known for the production of polymers and copolymers from conjugated diene monomers and aromatic and aliphatic alpha-olefin monomers. [0003] EP 816,386 describes olefin polymerization catalysts comprising transition metal compounds (preferably IIIA, IVA, VA, VIA, VIIA or VIII group or lanthanide transition metals, preferably titanium, zirconiu...
