Curable resin composition containing a saturated monooxirane compound, a solid polyanhydride, water and a soluble tertiary amine; and method of production and article
Abstract
Abstract LIQUID COATING AND MOLDING COMPOSITIONS ARE PROVIDED WHICH ARE CURABLE TO AN INFUSIBLE RESIN ARTICLE OR COATING OF IMPROVED (LIGHTER) COLOR. THE COMPOSITION COMPRISES A SOLUTION OF A SATURATED MONOXIRANE COMPOUND, FOR EXAMPLE, EPICHLOROHYDRIN, A SOLID POLYANHYDRIDE HAVING SUCCINIC ANHYDRIDE GROUPS (EXCLUDING AROMATIC ANHYDRIDES IN WHICH THE ALPHA CARBON ATOMS OF THE ANHYDRIDE GROUP ARE INCLUDED IN THE AROMATIC RING) FOR EXAMPLE, THE COPOLYMER OF A STRAIGHT CHAIN ALPHA-MONOOLEFIN AND A MALEIC ANHYDRIDE; WATER OR METHANOL; AND A SOLUBLE TERTIARY AMINE SUCH AS 3-PICOLINE. THE CURING RATE OF THE COMPOSITION IS CONTROLLED DEPENDING ON THE AMOUNT AND MANNER OF THE WATER OR METHANOL ADDITION. THE COMPOSITION SHOWS LESS SHRINKAGE AND WEIGHT LOSS DURING CURING COMPARED WITH THE SAME COMPOSITION MINUS THE WATER OR METHANOL. THUS, FOR EXAMPLE, FILM AND COATING FREE OF LIFTING AND ETCHING ARE OBTAINED.
