Heterophasic copolymer and method for the preparation thereof

Methods for preparing an impact copolymer by selecting a continuous phase polymer having a first melt flow rate and selecting a rubber phase polymeric material such that the final melt flow rate of the impact copolymer is within 2 g/10 min of the first melt flow rate. Impact copolymers made from suc...

Zusammenfassung:	Methods for preparing an impact copolymer by selecting a continuous phase polymer having a first melt flow rate and selecting a rubber phase polymeric material such that the final melt flow rate of the impact copolymer is within 2 g/10 min of the first melt flow rate. Impact copolymers made from such methods and films and molded articles produced from such impact copolymers are also included.
