Abstract
A poly(ether-carbonate)-based polymer and a medical device that includes such polymer, wherein the poly(ether-carbonate)-based polymer includes urethane, urea, or urethane-urea groups, hard segments, and soft segments, wherein the soft segments include poly(ether-carbonate) residues and at least one of polyisobutylene (PIB) residues and hydrogenated polybutadiene residues, and the hard segments include diisocyanate residues and optionally chain extender residues.
