Title
(EN) CATALYSTS FOR CROSSLINKING EPOXY RESINS
(FR) CATALYSEURS DE RÉTICULATION DE RÉSINES ÉPOXY
Abstract
(EN) A compound of formula (I): MXy, alone or in combination with a compound of formula (II): MXzL, useful as a catalyst for accelerating the crosslinking of a reactive epoxy monomer, oligomer or polymer to form an epoxy thermoset resin, is provided. In formulas (I) and (II), M represents a rare earth metal cation, X represents an anion of formula R-Z-O", wherein R represents a hydrocarbon radical optionally substituted with one or more halogen atom and -Z- represents -S(=O)2- or -O-S(=O)2-, z = y +1, and L represents Na+, H+, or a combination thereof.
(FR) Composé de formule (I) : MXy seul ou en combinaison avec un composé de formule (II) : MXzL, utile en tant que catalyseur pour accélérer la réticulation d'un monomère, d'un oligomère ou d'un polymère époxy réactif pour former une résine époxy thermodurcie. Dans les formules (I) et (II), M représente un cation de métal des terres rares, X représente un anion de formule R-Z-O", dans laquelle R représente un radical hydrocarboné éventuellement substitué par un ou plusieurs atomes d'halogène et -Z- représente -S(=O)2-ou -O-S(=O)2-, z = y + 1 et L représente Na+, H+, ou une combinaison de ceux-ci.
