Patent ID: 6858557

Claim:
A catalyst system for olefin polymerization comprising: (A) an inert support; (B) a metal coordination complex of the formula: wherein: (a) M is titanium; (b) Cp* is selected from the group consisting of cyclopentadienyl and R″ m -substituted cyclopentadienyl, bound in an η 5 bonding mode to M, wherein R″ is independently selected from the group consisting of alkyl of up to 20 carbon atoms and aryl of up to 20 carbon atoms and two adjacent R″ groups may join to form a ring and m is 1 to 4; (c) Z is selected from the group consisting of CR′ 2 , CR′ 2 CR′ 2 , SiR′ 2 , and SiR′ 2 SiR′ 2 , wherein each R′ is independently selected from the group consisting of alkyl of up to 20 carbon atoms, aryl of up to 20 carbon atoms, and mixtures thereof of up to 20 carbon atoms; (d) Y is NR, wherein R is selected from the group consisting of alkyl of up to 20 carbon atoms, aryl of up to 20 carbon atoms, and mixtures thereof of up to 20 carbon atoms; (e) X is, independently each occurrence, selected from the group consisting of halo, alkyl of up to 10 carbon atoms, aryl of up to 10 carbon atoms, aryloxy of up to 10 carbon atoms, alkoxy of up to 10 carbon atoms, and mixtures thereof of up to 10 carbon atoms; and (f) n is 2; and (c) an alkylalumoxane.
