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 29):
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 (1) M is a group 4 metal, preferably hafnium; (2) L 6  is a C 5 -C 20  heteroaryl group containing a Lewis base functionality, especially pyridine-2-yl or substituted pyridine-2-yl group or a divalent derivative thereof; (3) R 40  is selected from a C 1 -C 30  alkyl, cycloalkyl, heteroalkyl, cycloheteroalkyl, aryl and substituted derivatives thereof or a divalent derivative thereof; (4) T is a divalent bridging group comprising carbon and or silicon, preferably a C 1 -C 20  hydrocarbyl substituted methylene or silane group; (5) each X is independently a univalent anionic ligand, or two Xs are joined and bound to the metal atom to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand; (6) N is nitrogen; and (7) bonds, optional bonds and dative bonds are represented by lines, dotted lines and arrows, respectively.
