Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
210 words
A METHOD OF MAKING A MODIFIED POLYSTER RESIN COMPOSITION COMPRISING PROVIDING (A) A POLYESTER OF A GLYCOL WITH AN ALPHA, BETA-ETHYLENICALLY UNSATURATED DICARBOXYLIC ACID HAVING AN ACID VALUE OF 10 TO 100, MIXING THE SAID POLYESTER WITH (B) A COPOLYMERIZABLE ETHYLENICALLY UNSATURATED MONOMER, (C) A METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF OXIDES, HYDROXIDES AND ALKOXIDES IN WHICH THE ALKYL GROUP CONTAINS 1 TO 6CARBON ATOMS, OF MAGNESIUM, ALUMINUM AND CALCIUM, AND (D) AN ALIPHATIC MONOCARBOXYLIC ACID HAVING FROM 6 TO 24 CARBON ATOMS, AND HEATING THE RESULTING MIXTUER IN THE PRESENCE OF A POLYMERIZATION INHIBITOR AT A TEMPERATURE OF FROM 140 TO 250*F. FOR A PERIOD OF FROM 5 MINUTES TO 40 HOURS, WHEREBY THE SAID MONOCARBOXYLIC ACID BECOMES LINKED TO THE SAID POLYESTER THROUGH A METAL LINKAGE, TO PRODUCE A PLACTICIZED RESIN COMPOSITION CHARACTERIZED BY INCREASED VISCOSITY, THE AMOUNT OF SAID MONOMER (B) BEING FROM 5 TO 80% BY WEIGHT BASED ON THE ENTIRE WEIGHT OF THE COMPOSITION, THE AMOUNT OF SAID METAL COMPOUND (C) BEING FROM 0.1 TO 3 PARTS BY WEIGHT PER 100 PARTS BY WEIGHT OF UNMODIFIED POLYESTER (A), AND THE AMOUNT OF SAID MONOCARBOXYLIC ACID (D) BEING FROM 1 TO 15 PARTS BY WEIGHT PER 100 PARTS BY WEIGHT OF UNMODIFIED POLYESTER (A).
