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 2):
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 Formula (6): wherein (1) M is a group 4 metal, preferably hafnium; (2) N is nitrogen; (3) L 7  is a group that links R 50  to Z\u2032 by a three atom bridge with the central of the three atoms being a group 15 or 16 element that preferably forms a dative bond to M, and is a C 5 -C 20  heteroaryl group containing a Lewis base functionality, especially a divalent pyridinyl, substituted pyridinyl, quinolinyl, or substituted quinolinyl group; (4) Z\u2032 is a divalent linker group, (R 56 ) p C\u2014C(R 57 ) q , where R 56  and R 57  are independently selected from the group consisting of hydrogen, hydrocarbyls, substituted hydrocarbyls, and wherein adjacent R 56  and R 57  groups may be joined to form an aromatic or saturated, substituted or unsubstituted hydrocarbyl ring, wherein the ring has 5, 6, 7, or 8 ring carbon atoms and where the substituents on the ring can join to form additional rings, and p is 1 or 2 and q is 1 or 2; (5) R 50  and R 53  are each, independently, ER 54 R 55  with E being carbon, silicon or germanium, and each R 54  and R 55  being independently selected from the group consisting of hydrogen, hydrocarbyls, substituted hydrocarbyls, alkoxy, silyl, amino, aryloxy, halogen and phosphino, and R 54  and R 55  may be joined to form a saturated heterocyclic ring, or a saturated substituted heterocyclic ring where substitutions on the ring can join to form additional rings; (6) R 51  and R 52  are independently selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, silylcarbyls and substituted silylcarbyl groups; and (7) 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; 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 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; c) has an Mw of 50,000 g/mol or more; and d) has a Mw/Mn of less than 4.0.
