Abstract
A bioabsorbable synthetic polymer is exposed to a gas plasma in a chamber at a pressure substantially below atmospheric for a sufficient time to increase the hydrophobicity and/or cross-linking density of a surface layer thereof and thereby modify the rate at which the polymer will hydrolyze. An accordingly modified polymer is useful for surgical implants and wound closures.
