Abstract
Abstract COMPOSITIONS OF MONTHS-LONG CATALYZED POT LIFE AT ROOM TEMPERATURE AND HENCE ESPECIALLY SUITABLE FOR COATING LARGE OBJECTS, ARE MADE BY MIXING (A) THE PRODUCT OF THE UNCATALYZED HALF-ESTERIFICATION OF EPOXY RESIN WITH AN OLEFINICALLY UNSATURATED DICARBOXYLIC ACID ANHYDRIDE (E.G., MALEIC ANHYDRIDE), (B) A COREACTIVE VINYL MONOMER (E.G., STYRENE), (C) A POLYCARBOXYLIC ANHYDRIDE CONTAINING NO OLEIFINIC UNSATURATION (E.G., NADIC METHYL ANHYDRIDE (NMA), VISCOUS LIQUID METHYLBICYLCLO (2.2.1)HEPTENE-2,3DICARBOXYLIC ANHYDRIDE ISOMERS) AND (D) POLYMERIZATION CATALYSTS AND INHIBITORS. UPON HEATING, THE COMPOSITION CURES TO A THERMOSET RESIN. THE BASIC COMPOSITION IS MODIFIED WITH FILLERS AND ADDITIVES FOR USE AS POTTING COMPOUNDS, ENCAPSULANTS, CASTINGS, LAMINATE ADHESIVES, ETC.
