Abstract:
Catalyst systems with single site transition metal complexes (such as pyridyldiamido transition metal complexes), an activator, and a metal hydrocarbenyl chain transfer agent (preferably an aluminum vinyl-transfer agent) are disclosed for use in alkene polymerization.

Claim (Index 30):
A catalyst system comprising an activator; and aluminum vinyl transfer agent represented by the formula: Al(R\u2032) 3-v (R\u2033) v , wherein each R\u2032, independently, is a C 1  to C 30  hydrocarbyl group; each R\u2033, independently, is a C 4  to C 20  hydrocarbenyl group having an allyl chain end; v is from 0.01 to 3; and a transition metal complex represented by the formula: wherein M, T, N and X are as previously defined as in formula (5); each R 41 , R 42 , R 43 , and R 44  are independently hydrogen, halo, or an alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, aryl or silyl group, or one or more adjacent R 41 -R 44  may be joined together to form a fused ring derivative; R 45 -R 49  are independently hydrogen, or C 1 -C 10  alkyl, most preferably R 45  and R 49  are alkyl such as isopropyl or tert-butyl; T is preferably CR\u2032 50 R\u2032 51  where R\u2032 50  and R\u2032 51  are independently hydrogen, halogen, a C 1 -C 20  hydrocarbyl, most preferably, one of R\u2032 50  and R\u2032 51  is hydrogen and the other is a C 6 -C 20  aryl group, especially 2-isopropyl, phenyl or a fused polycyclic aryl group, most preferably anthracenyl; and bonds, optional bonds and dative bonds are represented by lines, dotted lines and arrows, respectively.
