Process for producing homopolymers or copolymers of conjugated dienes by contacting monomeric material including at least one conjugated diene with a catalyst system comprising (A) a first transition metal compound selected from Cr, Mo and W compounds, and a second transition metal compound selected from Fe, Co and Ni compounds, (B) a catalyst modifier and, optionally, (C) one or more catalyst activators.

Diene polymerisation

A process is disclosed for the preparation of zinc alkyl chain growth products via a catalyzed chain growth reaction of an alpha-olefin on a zinc alkyl, wherein the chain growth catalyst system employs a group 3-10 transition metal, or a group 3 main group metal, or a lanthanide or actinide complex, and optionally a suitable activator. The products can be further converted into alpha-olefins by olefin displacement of the grown alkyls as alpha-olefins from the zinc alkyl chain growth product, or into primary alcohols, by oxidation of the resulting zinc alkyl chain growth product to form alkoxide compounds, followed by hydrolysis of the alkoxides.
