Abstract: This invention concerns a process for increasing the hardening rates in the preparation of epoxide resins using dicarboxylic anhydrides as hardening agents. The increase in hardening rates is achieved by reacting mixtures of basic nitrogen-containing glycidyl compounds with di-carboxylic anhydrides. An optional aspect of the inventive process is to conduct the above reaction in the presence of alkyd resins and/or solvents.

Abstract: THIS INVENTION CONCERNS A PROCESS FOR INCREASING THE HARDENING RATES IN THE PREPARATION OF EPOXIDE RESINS USING DICARBOXYLIC ANHYDRIDES AS HARDENING AGENTS. THE INCREASE IN HARDENING RATES IS ACHIEVED BY REACTING MIXTURES OF BASIC NITROGEN-CONTAINING GLYCIDYL COMPOUNDS WITH DICARBOXYLIC ANHYDRIDES. AN OPTIONAL ASPECT OF THE INVENTIVE PROCESS IS TO CONDUCT THE ABOVE REACTION IN THE PESENCE OF ALKYD RESINS AND/OR SOLVENTS.
