Method for preparing and compositions of vinylized and/or vinylidenized epoxy resin esters

Abstract

Abstract METHODS AND COMPOSITIONS FOR WATER-DILUTABLE HEATCURABLE COATINGS COMPRISING: (I) VINYLIZED AND/OR VINYLIDENIZED COMPOUNDS OF PARTIAL ESTERS CONTAINING HYDROXYL GROUPS AND OPTIONALLY ALSO EPOXIDE GROUPS OBTAINED BY PARTIAL ESTERIFICATION OF COMPOUNDS CONTAINING EPOXIDE GROUPS AND OPTIONALLY HYDROXYL GROUPS WITH MONOCARBOXYLIC ACID MIXTURES HAVING A PREDOMINANT CONTENT OF UNSATURATED ALIPHATIC STRAIGHT CHAIN MONOCRABOXYLIC ACIDS AND/OR PARTIAL ESTERS REACTED EITH POLYBASIC CARBOXYLIC ACIDS IN SUCH A WAY THAT THE RESULTING EPOXIDE RESIN ESTERS CONTAINING FREE CARBOXYL GROUPS AND FREE HYDROXYL GROUPS ACQUIRE THE ABILITY TO BE DILUTED WITH WATER BY NEUTRALIZATION WITH AMMONIA OR STRONG ORGANIC NITROGEN BASES IN THE PRESENCE OF WATER; (II) AMMONIA OR STRONG ORGANIC NITROGEN BASES; (III) WATER; AND (IV) HEAT-CURABLE, WATER-SOLUBLE OR HYDROPHILIC LOW MOLECULAR WEIGHT ALDEHYDE CONDESATION PRODUCTS OF: (A) PHENOLIC RESOLS; (B) RESINS WHICH FORM AMINOPLASTS; AND (C) ETHERFIED PHENOLIC RESOLS.
