PROCESS FOR PREPARING A HIGH-MOLECULAR-WEIGHT REACTOR BLEND COMPRISING POLYPROPYLENE AND ETHYLENE-PROPYLENE COPOLYMER WITH MOLECULAR WEIGHT DISTRIBUTION IN THE RANGE FROM 6 TO 20

摘要

A high-molecular weight reactor blend of polypropylene and ethylene-propylene copolymer comprises an ethylene content of 0.1-2 wt%, a melt flow index (230/5) of not more than 5 dg/minute and a molecular weight distribution (Mw/Mn) of 6-20. Also claimed is a process for the production of the blend.
