Abstract:
A modified polyisobutylene-based polymer, method of making, and a medical device that includes such polymer, wherein the modified polyisobutylene-based polymer includes urethane, urea, or urethane-urea groups, hard segments, and soft segments, wherein the soft segments comprise phenoxy-containing polyisobutylene residues, and the hard segments include diisocyanate residues and optionally chain extender residues.
