Reinforced copolymers formed from a functionalized copolymer that undergoes a reactive extrusion process with an inorganic component to form the reinforced copolymer. The functionalized copolymer in the form of a block and/or graft copolymer includes hard segments and soft segments, where the soft segments are covalently bonded with a coupling agent either before or after copolymerization with the hard segments. The reinforced copolymer of the present disclosure can be suitable for use as a biomaterial and/or in medical devices.

La présente invention concerne des copolymères renforcés formés à partir d'un copolymère fonctionnalisé qui subit un processus réactif d'extrusion avec un composant inorganique de façon à former le copolymère renforcé. Le copolymère fonctionnalisé sous forme d'un copolymère bloc et/ou d'un copolymère greffé inclut des segments durs et des segments mous, lesquels segments mous étant liés par covalence avec un agent de couplage avant ou après copolymérisation avec les segments durs. Le copolymère renforcé de la présente invention semble convenir comme biomatériau et/ou à l'utilisation dans des dispositifs médicaux.
