Abstract
Supported heterometallocene catalysts wherein the support is a particulate polymeric material are provided. The catalysts have a transition metal complex containing at least one anionic, polymerization stable heteroatomic ligand associated with the transition metal and a boron activator compound deposited on the support. Polymeric supports used for the heterometallocene catalysts of the invention are homopolymers of ethylene and copolymers of ethylene and C3-8 α-olefins.
Claims21

- (a) a particulate ethylene homopolymer or ethylene-C3-8 α-olefin copolymer support;
- (b) a transition metal coordination complex containing at least one anionic polymerization-stable heteroatomic ligand;
- and
- (c) a boron activator compound.
