Acrylamide and aromatic hydrocarbon monomer modified interpolymers of maleinized oils

Claim 1

A METHOD OF FORMING A XYLENE SOLUBLE, NON-GELLED, TERNARY INTERPOLYMER, WHICH COMPRISES HEATING TO A TEMPERATURE OF ABOUT 75* C. TO ABOUT 150* C. A MIXTURE OF A LIQUID DILUENT AND (A) AN ESTER HAVING AN ACID VALUE BELOW ABOUT 15 AND BEING FORMED SUBSTANTIALLY COMPLETELY FROM (1) A POLYCARBOXYLIC ACID OF THE CLASS CONSISTING OF MALEIC ACID, FUMARIC ACID AND ITACONIC ACID, AND (2) A PARTIAL ESTER OF A POLYHYDRIC ALCOHOL AND A DRYING OIL FATTY ACID, SAID POLYHYDRIC ALCOHOL INITIALLY CONTAINING ABOUT 2 TO ABOUT 6 HYDROXYL GROUPS PER MOLECULE, ABOUT 25 TO ABOUT 50 PERCENT BY THE HYDROXYL GROUPS ORIGINALLY CHARACTERIZING THE POLYHYDRIC ALCOHOL BEING ESTERIFIED BY THE ETHYLENICALLY UNSATURATED POLYCARBOXYLIC ACID AND THE REST BEING ESTERIFIED BY THE DRYING OIL FATTY ACID; (B) A PAIR OF MONOMERS, ONE OF SAID MONOMERS BEING SELECTED FROM THE CLASS CONSISTING OF ACRYLAMIDE AND METHACRYLAMIDE, AND THE OTHER OF SAID MONOMERS BEING SELECTED FROM THE CLASS CONSISTING OF STYRENE, ALPHA METHYL STYRENE AND VINYL IOLUENE, THE MONOMER OF THE FIRST MENTIONED CLASS BEING PRESENT IN AN AMOUNT OF ABOUT 5 TO ABOUT 20 PERCENT BASED UPON THE MIXTURE, THE TWO MONOMERS OF THE PAIR COMPRISING ABOUT 10 TO ABOUT 100 PERCENT BY WEIGHT BASED UPON THE ESTER (A); AND (C) ABOUT 0.1 TO ABOUT 5 PERCENT BY WEIGHT BASED UPON THE INTERPOLYMERIZABLE MIXTURE OF A PEROXIDE CATALYST OF INTERPOLYMERIZATION, HEATING OF SAID MIXTURE BEING CONTINUED UNTIL CONVERSION OF THE MIXTURE OF SAID SOLUBLE, NON-GELLED, TERNARY INTERPOLYMER IS SUBSTANTIALLY COMPLETE.

Claim 2

A METHOD OF FORMING A XYLENE SOLUBLE, NON-GELLED, TERNARY INTERPOLYMER, WHICH COMPRISES HEATING TO A TEMPERATURE OF ABOUT 75* C. TO ABOUT 150* C. A MIXTURE OF A LIQUID DILUENT AND (A) AN ESTER HAVING AN ACID VALUE BELOW ABOUT 15 AND BEING FORMED SUBSTANTIALLY COMPLETELY FROM (1) A POLYCARBOXYLIC ACID OF THE CLASS CONSISTING OF MALEIC ACID, FUMARIC ACID AND ITACONIC ACID, AND (2) A PARTIAL ESTER OF A POLYHYDRIC ALCOHOL AND A DRYING OIL FATTY ACID, SAID POLYHYDRIC ALCOHOL INITIALLY CONTAINING ABOUT 2 TO ABOUT 6 HYDROXYL GROUPS PER MOLECULE, ABOUT 25 TO ABOUT 50 PERCENT BY THE HYDROXYL GROUPS ORIGINALLY CHARACTERIZING THE POLYHYDRIC ALCOHOL BEING ESTERIFIED BY THE ETHYLENICALLY UNSATURATED POLYCARBOXYLIC ACID AND THE REST BEING ESTERIFIED BY THE DRYING OIL FATTY ACID; (B) A PAIR OF MONOMERS, ONE OF SAID MONOMERS BEING SELECTED FROM THE CLASS CONSISTING OF ACRYLAMIDE AND METHACRYLAMIDE, AND THE OTHER OF SAID MONOMERS BEING SELECTED FROM THE CLASS CONSISTING OF STYRENE, ALPHA METHYL STYRENE AND VINYL IOLUENE, THE MONOMER OF THE FIRST MENTIONED CLASS BEING PRESENT IN AN AMOUNT OF ABOUT 5 TO ABOUT 20 PERCENT BASED UPON THE MIXTURE, THE TWO MONOMERS OF THE PAIR COMPRISING ABOUT 10 TO ABOUT 100 PERCENT BY WEIGHT BASED UPON THE ESTER (A); AND (C) ABOUT 0.1 TO ABOUT 5 PERCENT BY WEIGHT BASED UPON THE INTERPOLYMERIZABLE MIXTURE OF A PEROXIDE CATALYST OF INTERPOLYMERIZATION, HEATING OF SAID MIXTURE BEING CONTINUED UNTIL CONVERSION OF THE MIXTURE OF SAID SOLUBLE, NON-GELLED, TERNARY INTERPOLYMER IS SUBSTANTIALLY COMPLETE.
