ABSTRACT:
A generally hydrophobic polyester article is provided with a generally hydrophilic surface by contacting said general hydrophobic polyester with a copolymeric material while said polyester is at a temperature above its melting point. The copolymeric composition comprises a generally hydrophobic moiety and a generally hydrophilic moiety. Also disclosed is a method for imparting the hydrophilic surface to a generally hydrophobic polyester which method comprises contacting a generally hydrophobic polyester with a copolymeric material while said generally hydrophobic polyester is at a temperature above its melting point. In one preferred embodiment the generally hydrophobic polyester is contacted with said copolymeric composition immediately after said polyester has been extruded and while said polyester is undergoing die swell.
