Abstract

La présente invention concerne une substance contenant de multiple groupes fonctionnels époxy, copolymérisés par les monomères suivants, en parties en poids : 10 à 90 parties de monomère styrène; 10 à 90 parties de monomère (méthyl)acrylate de glycidyle, "multiple" signifiant que chaque molécule contient en moyenne 3 à 100 groupes fonctionnels époxy. La présente invention concerne également un procédé de préparation de la substance contenant de multiple groupes fonctionnels époxy. L'invention concerne également un terpolymère de la substance contenant de multiple groupes fonctionnels époxy, du dioxyde de carbone et de l'époxy propane et un procédé de préparation associé. Le rendement du terpolymère préparé au moyen du procédé de la présente invention est grandement amélioré, la température de traitement à chaud est sensiblement améliorée, et le terpolymère préparé peut être utilisé seul comme matière plastique courante.
