Water dispersible and water soluble alkyds comprising polyalkylene glycol, monocarboxylic acid, dicarboxylic acid, and polyol

Claim 1

THE PROCESS OF PRODUCING A SELF-DISPERSIBLE AND WATER SOLUBLE NON-OXIDIZING ALKYLD RESIN, WHICH COMPRISES: (I) FORMING A FIRST MIXTURE OF (A) POLYALKYLENE GLYCOL SELECTED FROM THE GROUP CONSISTING OF POLYETHYLENE GLYCOL AND POLYPROPYLENE GLYCOL HAVING A MOLECULAR WEIGHT BETWEEN 600 AND 6,000; (B) MONOCARBOXYLIC ACID SELECTED FROM THE GROUP CONSISTING OF (1) NONOXIDIZING FATTY ACIDS OF FROM 6-18 CARBON ATOMS, (2) AROMATIC AND SATURATED ALIPHATIC MONOCARBOXYLIC ACIDS OF FROM 7-14 CARBON ATOMS, OTHER THAN FATTY ACIDS, AND (3) MIXTURES OF (1) AND (2); AND (C) MATERIAL SELECTED FROM THE GROUP CONSISTING OF AROMATIC DICARBOXYLIC ACIDS, SATURATED ALIPHATIC DICARBOXYLIC ACIDS, AND ANHYDRIDES THEREOF, OF FROM 4-10 CARBON ATOMS, AND MIXTURES OF THE SAME; AND REACTING SAID FIRST MIXTURE AT TEMPERARTURES BETWEEN 410* AND 550*F.; (II) SUBSEQUENTLY ADDING TO THE MIXTURE AT LEAST ONE POLYHYDRIC ALCOHOL, OTHER THAN SAID POLYALKYLENE GLYCOLS, TO THEREBY FORM A SECOND MIXTURE, SAID POYHYDRIC ALCOHOL HAVING AT LEAST TWO HYDROXYL GROUPS AND CONTAINING 2-8 CARBON ATOMS, REACTING SAID SECOND MIXTURE AT TEMPERATURES BETWEEN 410* AND 550* F., CONTINUING SAID REACTING UNTIL AN ACID NUMBER OF NOT MORE THAN ABOUT 10 IS OBTAINED, AND NEUTRALIZING THE RESIDUAL ACIDITY WITH AN ACID NEUTRALIZING AGENT WHICH IS VOLATILE AT TEMPERATURES BELOW ABOUT 375* F., THEREBY EFFECTING THE PRODUCTION OF SAID ALKYD RESIN.
