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 25):
A catalyst system comprising a pyridyldiamido transition metal complex represented by the formula: wherein: M is a Group 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 metal; E is selected from carbon, silicon, or germanium; X is an anionic leaving group; L is a neutral Lewis base; R 1  and R 13  are each independently selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, and silyl groups; R 2  R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11  and R 12  are each independently selected from the group consisting of hydrogen, hydrocarbyls, alkoxy, silyl, amino, aryloxy, substituted hydrocarbyls, halogen, and phosphino; n is 1 or 2; m is 0, 1, or 2; and two X groups may be joined together to form a dianionic group; two L groups may be joined together to form a bidentate Lewis base; an X group may be joined to an L group to form a monoanionic bidentate group; R 7  and R 8  may be joined to form a ring; R 10  and R 11  may be joined to form a ring; 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.
