The invention provides a polymer comprising urethane groups, urea groups, or combinations thereof, and one or more sacrificial moieties that preferentially oxidize relative to all other moieties in the polymer, or an oxidised form thereof. Such polymers have been found to possess improved biostability and are particularly suited to use in medical devices.
