Patent ID: 7977435

Claim:
A process for producing a propylene polymer composition comprising: (a) contacting a catalyst, at least two electron donors fed as a blend, propylene monomer and a comonomer selected from ethylene and C 4 to C 10 alpha olefins in a first reaction zone; (b) polymerizing the propylene monomer and the comonomer in the first reaction zone to form a propylene copolymer; (c) transferring at least a portion of a first reaction zone effluent comprising propylene copolymer, catalyst and at least one electron donor to a second reaction zone; (d) introducing additional propylene monomer to the first reaction zone effluent in the second reaction zone; (e) polymerizing propylene monomer in the second reaction zone to form a propylene homopolymer in the second reaction zone; and (f) recovering from the second reaction zone a propylene polymer composition comprising from 0.5 to 7.5 wt% comonomer and exhibiting: MFR of from 5 to 10 dg/min; xylene solubles of at least 5 wt%; C 1/2T less than or equal to 270 seconds; MWD of from 6 to 10; σ dis of from 3.5° C. to 7.5° C.; T m less than or equal to 160° C.; and T c greater than 112° C.
