Abstract:
This invention relates to the use of pyridyldiamido and/or quinolinyldiamido transition metal complexes and catalyst systems with an activator and a metal hydrocarbenyl chain transfer agent, such as an aluminum vinyl-transfer agent (AVTA), to produce branched propylene polymers, preferably propylene-ethylene copolymers or propylene-ethylene-diene monomer copolymers.

Claim (Index 16):
A propylene copolymer comprising from about 99 to 30 wt % propylene, from 1 to 70 wt % ethylene, from 0 to 20 wt % diene monomer, and a remnant of a metal hydrocarbenyl chain transfer agent wherein the metal hydrocarbenyl chain transfer agent is represented by formula:\n Al(R\u2032) 3-v (R\u2033) v  wherein each R\u2032, independently, is a C 1 -C 30  hydrocarbyl group; each R\u2033, independently, is a C 4 -C 20  hydrocarbenyl group having an end-vinyl group; and v is from 0.1 to 3;\n wherein said branched propylene copolymer: a) has a g\u2032 vis  of less than 0.97; b) is essentially gel free (such as 5 wt % or less of xylene insoluble material); c) has an Mw of 50,000 g/mol or more; and d) has a Mw/Mn of less than 4.0.
