A curable melt blended composition and a method of making the composition by melt blending a thermoplastic polymer comprising polyphenylene ether (PPE) polymer and a polystyrene polymer, preferably high impact polystyrene (HIPS), and optionally a compatibilizer, with an uncured epoxy component, comprising a curable epoxy and an epoxy curing agent, at a temperature greater than 150 ~C and without addition of solvent wherein the epoxy component of the resulting curable melt blended composition remains substantially uncured.
Composition mélangée fondue durcissable et procédé permettant de préparer ladite composition. Le procédé consiste à mélanger à l'état fondu un polymère thermoplastique, comprenant un polymère de polyphénylènéther (PPE) et un polymère de polystyrène, de préférence d'un polystyrène choc (HIPS), et éventuellement un agent de compatibilité, avec un composant époxy non durci, comprenant une résine époxy durcissable et un agent de cuisson de l'époxy, à une température supérieure à 150 ·C et sans addition de solvant. Le composant époxy de la composition mélangée fondue durcissable reste sensiblement non durci.
