The present invention pertains to copolymers having one or more polyisobutylene segments and one or more biodegradable polymer segments, to methods of making such copolymers, to medical articles that contain such copolymers, and to methods of making such medical articles. According to certain aspects of the invention, copolymers are provided, which comprise a plurality of polyisobutylene segments and a plurality of biodegradable polymer segments. According to certain aspects of the in-vention, copolymers are provided, which comprise urethane linkages, urea linkages, amide linkages, ester linkages, anhydride linkages, carbonate linkages, linkages commonly described as "click" chemistry linkages, and combinations of two or more types of such linkages.
La présente invention porte sur des copolymères comportant un ou plusieurs segments de polyisobutylène et un ou plusieurs segments de polymère biodégradable, sur des procédés de production de tels copolymères, sur des articles médicaux contenant de tels polymères et sur des procédés de fabrication de tels articles médicaux. L'invention concerne, selon certains aspects, des copolymères comprenant une pluralité de segments de polyisobutylène et une pluralité de segments polymères biodégradables. L'invention concerne, selon certains aspects, des copolymères, comprenant des liaisons uréthane, des liaisons urée, des liaisons amides, des liaisons esters, des liaisons anhydrides, des liaisons carbonates, des liaisons couramment décrites comme étant des liaisons de chimie « déclic » et des combinaisons de deux types de telles liaisons ou plus.
