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 1):
A process to produce branched propylene copolymers comprising:\n 1) contacting monomer comprising propylene, ethylene and optional diene with a catalyst system comprising an activator, a metal hydrocarbenyl chain transfer agent, and one or more catalyst complexes represented by the Formulae I and II; wherein: M is a Group 3, 4, 5, 6, 7, 8, 9, or 10 metal; E is chosen from C(R 2 ) or C(R 3 )(R 3\u2032 ); X is an anionic leaving group; L is a neutral Lewis base; R 1  and R 13  are independently selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, and silyl groups; R 2  is a group containing 1-10 carbon atoms that is optionally joined with R 4  to form an aromatic ring; R 3 , R 3\u2032 , 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; J is a divalent group that forms a three-atom-length bridge between the pyridine ring and the amido nitrogen; n is 1 or 2; M is a 0, 1, or 2; two X groups optionally join together to form a dianionic group; two L groups optionally join together to form a bidentate Lewis base; an X group optionally join to an L group to form a monoanionic bidentate group; adjacent groups from the following R 3 , R 3\u2032 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , and R 12  may be joined to form a ring; where the metal hydrocarbenyl chain transfer agent is one or more aluminum vinyl transfer agents, AVTA, represented by formula:\n Al(R\u2032) 3-v (R\u2033) v  \n 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; and 2) obtaining branched propylene copolymers 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 the metal hydrocarbenyl chain transfer agent, 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.
