Abstract

L'invention concerne un procédé de modification de la rhéologie d'une résine thermoplastique, comprenant les étapes consistant à utiliser une résine thermoplastique et à mélanger des particules de résine d'interpolymère avec la résine thermoplastique. La résine d'interpolymère contient un polymère styrénique intercalé dans une polyoléfine, de sorte que la résine thermoplastique est présente sous la forme d'une phase continue et la résine d'interpolymère est présente sous la forme d'une phase dispersée. Le procédé permet d'obtenir une résine thermoplastique à rhéologie modifiée présentant des caractéristiques physiques améliorées.
