Method for hardening an epoxy having at least two 1,2-epoxy groups
Abstract
Abstract EPOXY RESINS ARE HARDENED WITH PRIMARY, SECONDARY OR TERTIARY AMINES, WITH ORGANIC ACID ANHYDRIDES OR WITH PHENOLS. A CATALYST MAY BE USED. ACCORDING TO THE INVENTION A POLYFUNCTIONAL EPOXY RESIN I.E. AN EPOXY RESIN WITH ON THE AVERAGE AT LEAST TWO EPOXY GROUPS PER MOLECULE IS HARDENED BY REACTING IT WITH AN A-HALOGENALKYL ETHER THAT ON THE AVERAGE HAS AT LEAST TWO A-HALOGENALKYL ETHER GROUPS IN THE MOLECULE. IN FIG. 1 THE REACTION OF AN A-CHLOROALKYL ETHER IN WHICH ALKYL IS METHYL AND IN WHICH TWO A-CHLOROMETHYL GROUPS ARE PRESENT IN THE MOLECULE WITH AN EPOXY COMPOUND IS DEPICTED BUT FOR REASONS OF CLEARNESS THE EPOXY COMPOUND SHOWN HAS ONLY ONE EPOXY GROUPS. ACCORDING TO THE INVENTION TWO SUCH GROUPS MUST AT LEAST BE PRESENT. R''" IS A PHENYL GROUP. CATALYSTS MAY BE USED IN THE HARDENING PROCESS ACCORDING TO THE INVENTION.
