Process for preparing a fibril-reinforced polyolefin film and olefin polymer film so prepared.

摘要

A fibril reinforced olefin polymer is made of a web of randomly-dispersed olefin polymer fibrils which are heated under an applied pressure to form a fused polymer film having a small percentage of unmelted fibrils therein. The film has a higher tensile strength than a solvent cast film prepared from the same olefin polymer.
