Unsaturated carboxylic acids in interpolymer resins

Claim 1

A METHOD FORMING A XYLENE-SOLUBLE, UNGELLED INTERPOLYMER RESIN CHARACTERIZED BY ITS ABILITY TO DRY TO A HARD, CLEAR FILM, AND WHICH IS COMPATIBLE WITH AMINE-ALDEHYDE RESINS, WHICH METHOD COMPRISES THE STEPS OF DISSOLVING IN NONREACTIVE SOLVENT, A MIXTURE CONSISTING ESSENTIALLY OF (A) AN ESTER WHICH HAS AN ACID NUMBER BELOW 15 AND IN WHICH THE ACID COMPONENT IS AN ALPHA-BETA ETHYLENICALLY UNSATURATED DICARBOXYLIC ACID AND THE ALCOHOL COMPONENT IS AN ESTER OF A POLYHYDRIC ALCOHOL HAVING FROM 2 TO 6 HYDROXYL GROUPS, AND A DRYING OIL ACID, THE ESTERS FORMED HAVING A FATTY ACID CONTENT, CALCULATED UPON THE BASIS OF EQUIVALENT CLYCERIDE OIL, OF ABOUT 75 TO ABOUT 90 PERCENT BY WEIGHT OF THE TOTAL MIXTURE OF REACTIVE COMPONENTS OF THE ESTER SYSTEM, AND THE ETHYLENICALLY UNSATURATED POLYCARBOXYLIC ACID ESTER GROUPS IN THE MOLECULE AND THE RESULTING ESTER OF THE UNSATURATED DICARBOXYLIC ACID AND THE FATTY ACID CONSTITUTING ABOUT 10 TO ABOUT 25 PERCENT BY WEIGHT OF THE TOTAL ESTER PRODUCT? (B) ABOUT 5 PERCENT TO ABOUT 80 PERCENT BY WEIGHT BASED UPON THE ESTER COMPONENT OF A MONOMER OF THE CLASS CONSISTING OF VINYL TOLUENE, STYRENE, A MIXTURE OF STYRENE AND ALPHA METHYL STYRENE, METHYL METHACRYLATE, A MIXTURE OF STYRENE AND BUTADIENE, A MIXTURE OF STYRENE AND ACRYLONITRILE, A MIXTURE OF STYRENE AND VINYL ETHER, A MIXTURE OF STYRENE AND VINYL BUTYL ETHER, A MIXTURE OF VINYL ACETATE AND VINYL CHLORIDE, VINYL ACETATE, A MIXTURE OF STYRENE AND METHYL METHACRYLATE, A MIXTURE OF ACRYLONITRILE AND ALPHA METHYL STYRENE, AND A MIXTURE OF STYRENE AND CYCLOHEXENE, AND (C) ABOUT 0.5 TO ABOUT 5 PERCENT BY WEIGHT BASED UPON THE INTERPOLYMERIZABLE MIXTURE OF AN ETHYLENICALLY UNSATURATED CARBOXYLIC ACID SELECTED FROM THE GROUP CONSISTING OF ACRYLIC ACID, METHACRYLIC ACID, CROTONIC ACID, ISOCRONTONIC ACID, VINYL ACETIC ACID, ETHACID, FUMARIC ACID, ITACONIC ACID, AND METHYL MALEIC ACID, AND A PEROXIDIC CATALYST OF ADDITION INTERPOLYMERIZATION OF THE MIXTURE, THE CATALYST BEING PRESENT IN AN AMOUNT OF 0.1 TO 5 PERCENT BY WEIGHT BASED UPON THE INTERPOLYMERIZABLE MIXTURE, AND REFLUXING THE MIXTURE UNTIL SAID INTERPOLYMER IS FORMED, ALL OF COMPONENT (C) BEING REACTED WITH COMPONENTS (A) AND (B).

Claim 2

A METHOD FORMING A XYLENE-SOLUBLE, UNGELLED INTERPOLYMER RESIN CHARACTERIZED BY ITS ABILITY TO DRY TO A HARD, CLEAR FILM, AND WHICH IS COMPATIBLE WITH AMINE-ALDEHYDE RESINS, WHICH METHOD COMPRISES THE STEPS OF DISSOLVING IN NONREACTIVE SOLVENT, A MIXTURE CONSISTING ESSENTIALLY OF (A) AN ESTER WHICH HAS AN ACID NUMBER BELOW 15 AND IN WHICH THE ACID COMPONENT IS AN ALPHA-BETA ETHYLENICALLY UNSATURATED DICARBOXYLIC ACID AND THE ALCOHOL COMPONENT IS AN ESTER OF A POLYHYDRIC ALCOHOL HAVING FROM 2 TO 6 HYDROXYL GROUPS, AND A DRYING OIL ACID, THE ESTERS FORMED HAVING A FATTY ACID CONTENT, CALCULATED UPON THE BASIS OF EQUIVALENT CLYCERIDE OIL, OF ABOUT 75 TO ABOUT 90 PERCENT BY WEIGHT OF THE TOTAL MIXTURE OF REACTIVE COMPONENTS OF THE ESTER SYSTEM, AND THE ETHYLENICALLY UNSATURATED POLYCARBOXYLIC ACID ESTER GROUPS IN THE MOLECULE AND THE RESULTING ESTER OF THE UNSATURATED DICARBOXYLIC ACID AND THE FATTY ACID CONSTITUTING ABOUT 10 TO ABOUT 25 PERCENT BY WEIGHT OF THE TOTAL ESTER PRODUCT? (B) ABOUT 5 PERCENT TO ABOUT 80 PERCENT BY WEIGHT BASED UPON THE ESTER COMPONENT OF A MONOMER OF THE CLASS CONSISTING OF VINYL TOLUENE, STYRENE, A MIXTURE OF STYRENE AND ALPHA METHYL STYRENE, METHYL METHACRYLATE, A MIXTURE OF STYRENE AND BUTADIENE, A MIXTURE OF STYRENE AND ACRYLONITRILE, A MIXTURE OF STYRENE AND VINYL ETHER, A MIXTURE OF STYRENE AND VINYL BUTYL ETHER, A MIXTURE OF VINYL ACETATE AND VINYL CHLORIDE, VINYL ACETATE, A MIXTURE OF STYRENE AND METHYL METHACRYLATE, A MIXTURE OF ACRYLONITRILE AND ALPHA METHYL STYRENE, AND A MIXTURE OF STYRENE AND CYCLOHEXENE, AND (C) ABOUT 0.5 TO ABOUT 5 PERCENT BY WEIGHT BASED UPON THE INTERPOLYMERIZABLE MIXTURE OF AN ETHYLENICALLY UNSATURATED CARBOXYLIC ACID SELECTED FROM THE GROUP CONSISTING OF ACRYLIC ACID, METHACRYLIC ACID, CROTONIC ACID, ISOCRONTONIC ACID, VINYL ACETIC ACID, ETHACID, FUMARIC ACID, ITACONIC ACID, AND METHYL MALEIC ACID, AND A PEROXIDIC CATALYST OF ADDITION INTERPOLYMERIZATION OF THE MIXTURE, THE CATALYST BEING PRESENT IN AN AMOUNT OF 0.1 TO 5 PERCENT BY WEIGHT BASED UPON THE INTERPOLYMERIZABLE MIXTURE, AND REFLUXING THE MIXTURE UNTIL SAID INTERPOLYMER IS FORMED, ALL OF COMPONENT (C) BEING REACTED WITH COMPONENTS (A) AND (B).
