POLYOLEFIN ARTICLES AND A METHOD OF MAKING

摘要

A generally hydrophobic polyolefin article is provided with a modified surface by contacting said generally hydrophobic polyolefin with a copolymeric material while said polyolefin is at a temperature above its glass transition temperature. The copolymeric composition comprises a generally hydrophobic moiety and a modifying moiety. Also disclosed is a method for imparting the modified surface to a generally hydrophobic polyolefin which method comprises contacting a generally hydrophobic polyolefin with a copolymeric material while said generally hydrophobic polyolefin is at a temperature above its glass transition temperature. In one preferred embodiment, the generally hydrophobic polyolefin is contacted with said copolymeric composition immediately after said polyolefin has been extruded and while said polyolefin is undergoing die swell.
