Abstract

L'invention concerne une dispersion composite essentiellement constituée d'une phase continue de caoutchouc vulcanisé et d'une phase dispersée de résine. On peut élaborer la dispersion par fusion-pétrissage de résine et de caoutchouc vert (en particulier, composition de caoutchouc contenant un générateur radicalaire et un promoteur de vulcanisation), puis par moulage du composé résultant, avec vulcanisation ou réticulation du caoutchouc vert. La résine considérée comporte des atomes actifs (par exemple, résine thermoplastique du type résine polyamide, résine thermodurcissable, ou résine réticulée ou durcie). Dans la dispersion considérée, le caoutchouc constitue la phase matricielle, et un certain nombre de particules de résine dispersée viennent à la surface, moyennant quoi la surface de la dispersion présente des propriétés de glissement ou autres caractéristiques inhérentes à la résine, sans perdre les caractéristiques propres au caoutchouc.
