Patent ID: 7714070

Claim:
A process for producing a polymer blend, said process comprising: polymerizing propylene in the presence of a Ziegler Natta catalyst in a first stage of a two stage reactor train to produce a homopolymer having a xylene solubles content of less than 3%; transferring the homopolymer to a second stage of the two stage reactor train; and polymerizing propylene and ethylene in said second stage in the presence of the homopolymer to produce a propylene/ethylene random copolymer having an ethylene content of from about 0.5% to about 7%, to produce a blend of the homopolymer and random copolymer; wherein the blend comprises from about 70 to about 95% by weight of the homopolymer and from about 5 to about 30% by weight of the random copolymer.
