Abstract

L'invention concerne un composite biodégradable hautement compatibilisé présentant une résistance élevée aux chocs comprenant : (a) une matrice polymère possédant un ou plusieurs polymères biodégradables ; (b) une ou plusieurs charges ; et (c) des initiateurs de radicaux libres fabriqués par l'intermédiaire d'un procédé d'extrusion réactive en une étape. L'invention porte sur un procédé de réaction à radicaux libres in situ de fabrication du composite biodégradable, comprenant les étapes (a) (1) de mélange d'un ou de plusieurs polymères biodégradables et d'un initiateur de radicaux libres ; (2) de fusion de (1) ce qui permet de fabriquer la matrice biodégradable hautement compatibilisée, (b) de mélange des composites de l'étape (a) et des charges ou des deuxièmes polymères biodégradables, ce qui permet de fabriquer le composite biodégradable. En outre, des nanomélanges sont préparés avec succès dans la présente invention, ce qui permet d'améliorer la compatibilité des différents composants.
