Abstract:
This invention relates to the use of 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-ethylene-diene terpolymers.

Claim (Index 1):
A process to produce branched ethylene, propylene-diene terpolymers comprising:\n 1) contacting monomers comprising propylene, ethylene and diene with a catalyst system comprising an activator, a metal hydrocarbenyl chain transfer agent, and one or more catalyst complexes represented by the Formula (Ia) or (IIa): wherein: M is a Group 3, 4, 5, 6, 7, 8, 9, or 10 metal; J is a three-atom-length bridge between the quinoline and the amido nitrogen; 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 independently selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, and silyl groups; R 2 * and R 3  through R 12  are 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 n+m is not greater than 4; any two adjacent R groups (e.g., R 1  & R 2 , R 2  & R 3 , etc.) may be joined to form a substituted or unsubstituted hydrocarbyl or heterocyclic ring, where the ring has 5, 6, 7, or 8 ring atoms and where substitutions on the ring can join to form additional rings; any two X groups may be joined together to form a dianionic group; any two L groups may be joined together to form a bidentate Lewis base; and an X group may be joined to an L group to form a monoanionic bidentate group; wherein 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 propylene copolymers comprising from about 98.9 to 30 wt % propylene, from 1 to 70 wt % ethylene, from 0.5 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 0.90; b) is essentially gel free; c) has an Mw of 250,000 g/mol or more; d) has a Mw/Mn of greater than 3.0; and e) has an Mz of 850,000 g/mol or more; wherein the process has a diene conversion of at least 15% and the ratio of the metal hydrocarbenyl chain transfer agent to the one or more catalyst complexes is at least 100:1.
