Abstract DRAWING 1. AN OXIDATIVELY STABILIZED COMPOSITION EXHIBITING OUTSTANDING RESISTANCE TO OXIDATIVE DEGRADATION WHICH COMPRISES IN COMBINATION: (A) A MAJOR PORTION OF A C2 TO C8 THERMOPLASTIC OR ELASTOMERIC POLYOLEFIN CONSTITUENT HAVING A GREATER TENDENCY TO OXIDATIVE DEGRADATION THAN SAID COMPOSITION; (B) AT LEAST ONE CONVENTIONAL ANTIOXIDANT STABILIZER SYSTEM; AND (C) SUFFICIENT C3 TO C10 UNSATURATED CARBOXYLIC ACID GRAFTED C3 TO C8 THERMOPLASTIC OR ELASTOMERIC POLYOLEFIN ADDITIVE TO INCORPORATE FROM ABOUT .05 TO 1.0 WEIGHT PERCENT OF GRAFTED COMPONENT INTO SAID CONSTITUENT POLYOLEFIN WHEREIN SAID ADDITIVE HAS BEEN PREPARED BY EXTRUDER GRAFTING OF A BASE POLYOLEFIN AND SAID ADDITIVE IS DEGRADED IN A MOLECULAR WEIGHT FROM SAID BASE POLYOLEFIN AS EVIDENCED BY AN INCREASE OF AT LEAST 25% IN THE MFR OF SAID ADDITIVE AS COMPARED TO THE MFR OF SAID BASE POLYOLEFIN.
