BLENDS OF GRAFT-MODIFIED SUBSTANTIALLY LINEAR ETHYLENE POLYMERS AND OTHER THERMOPLASTIC POLYMERS

摘要

Blends of substantially linear ethylene polymers, for example, polyethylenesprepared by constrained geometry catalysis, which aregrafted with one or more olefinically unsaturated organic compounds, forexample, maleic anhydride and another thermoplastic polymer,for example, a polyester or a polyamide demonstrate desirable impactproperties at both ambient and low temperatures (for example, -30°C).
