摘要： Propylene polymerization processes, polymers and films formed therefrom are described herein. The propylene polymerization processes generally include contacting propylene and an amount of ethylene with a first metallocene catalyst and a second metallocene catalyst within a polymerization reaction vessel to form a propylene based polymer, wherein the amount is an amount effective to form the propylene based polymer including from about 2 wt.% to about 6 wt.% ethylene, the second metallocene catalyst is capable of incorporating a greater amount of ethylene into the propylene based polymer than the first metallocene catalyst and wherein the first metallocene catalyst is capable of forming a propylene/ethylene random copolymer exhibiting a melting temperature that is greater than that of a propylene/ethylene random copolymer formed from the second metallocene catalyst.
