Title:
ETHYLENE/ alpha -OLEFIN POLYMER BLENDS COMPRISING COMPONENTS WITH DIFFERING ETHYLENE CONTENTS
Document Type and Number:
WIPO Patent Application WO2001085838
Kind Code:
A3
Abstract:
An ethylene/ alpha -olefin polymer blend is described comprising first and second ethylene/a-olefin polymer components in which the ethylene content of the first component is at least 10 weight percent different than the ethylene content of the second component. These blends exhibit an improved combination of low temperature, pellet flow, compression set, melt strength and/or shape retention properties as compared to either component, or an ethylene/ alpha -olefin polymer blend of similar composition but in which the ethylene content of each component is substantially the same.
