A star-branched diene rubber, the process for making such a rubber and its use in high impact polystyrene (HIPS) and acrylonitrile butadiene styrene (ABS) polymers.

Star-branched diene rubber

A metal complex of the formula (1) CyLMZ(A)(1), wherein M is a group 4 metal Z is an anionic ligand, p is number of 1 to 2, preferably 2, Cy is a cyclopentadienyl-type ligand substituted with at least one aliphatic C-Chydrocarbyl group, which is bonded to the cyclopentadienyl-type ligand, in particular to its cyclopentadienyl ring, via a secondary, a tertiary or quaternary carbon atom and, L is an amidinate ligand of the formula (2), wherein the amidine-containing ligand is covalently bonded to the metal M via the imine nitrogen atom, and Sub1 is a substituent comprising a group 14 atom through which Sub1 is bonded to the imine carbon atom and Sub2 is a substituent comprising a heteroatom of group 15, through which Sub2 is bonded to the imine carbon atom and A is a neutral Lewis base ligand selected from the list consisting of ether, thioether, amine, tertiary phosphane, imine, nitrile and isonitrile, wherein the number of said metal ligands 'n' is in the range of 0 to the amount that specifies the 18-electron rule.
