Abstract 1. A PROCESS FOR PRODUCING WATER SOLUBLE SYNTHETIC RESINS COMPRISING THE STEPS: (A) FORMING A WATER INSOLUBLE EPOXY-FREE PRECONDENSATE HAVING REACTIVE HYDROXYL GROUPS BY REACTING AN ELEVATED TEMPERATURE; (1) A POLYEPOXIDE HAVING AN ETHER LINKAGE AND A MAXIMUM OF TWO EPOXIDE GROUPS PER MOLECULE, SAID POLYEPOXIDE HAVING A MOLECULAR WEIGHT OF FROM 200 TO 3,000. (2) A HEAT REACTIVE COMPOUND COMPRISING A THERMOSETTING MATERIAL HAVING A REACTIVE HYDROXYL GROUP TO PREFERENTIALLY REACT WITH SAID EPOXIDE GROUP SELECTED FROM THE GROUP CINSISTING OF PHENOLIC RESINS, AMINOPLAST RESINS WHICH ARE ALDEHYDE CONDENSATION PRODUCTS OF MELAMINE, GUANAMINES, UREA, UNETHERIFIED OR ETHERFIED WITH MONO- OR POLYHYDRIC ALCOHOLS, AND ETHERFIED AND NONETHERIIED METHYLOL COMPOUNDS OF ACRYL AMIDE AND METHACRYLAMIDE POLYMERS, (B) THEREAFTER REACTING THE PRECONDENSATE FORMED IN (A) WITH A POLYCARBOXYLIC ACID HAVING AT LEAST TWO CARBOXYL GROUPS PER MOLECULE OR ANHYDRIDES OF SAID ACID, THE WEIGHT RATIO BETWEEN THE PRECONDENSATE AND THE POLYCARBOXYLIC ACID BEING SUFFICIENT TO PRODUCE A REACTIVE PRODUCT HAVING AN ACID NUMBER OF FROM ABOUT 40 TO 150; (C) SOLUBILIZING THE WATER INSOLUBLE REACTION PRODUCT OF (B) BY ADDING A NITROGEN BASE THEREBY NEUTRALIZING THE FREE CARBOXYL GROUPS.
