| abstract | 1. A STABILIZED COPOLYETHERESTER COMPOSITION CONSISTING ESSENTIALLY OF (A) A COPOLYETHERESTER HAVING A MULTIPLICITY OF RECURRING LONG CHAIN ESTER UNITS AND SHORT CHAIN ESTER UNITS JOINED HEAD-TO-TAIL THROUGH ESTER LINKAGES, SAID LONG CHAIN ESTER UNITS BEING REPRESENTED BY THE FORMULA -O-G-OOC-R-CO- AND SAID SHORT CHAIN UNITS BEING REPRESENTED BY THE FORMULA -O-D-OOC-R-CO- WHERE G IS A DIVALENT RADICAL REMAINING AFTER THE REMOVAL OF TERMINAL HYDROXYL GROUPS FROM A POLY(ALKYLENE OXIDE) GLYCOL HAVING A MOLECULAR WEIGHT OF ABOUT 400-600 AND A CARBON TO OXYGEN RATIO OF ABOUT 2.0--4.3; R IS A DIVALENT RADICAL REMAINING AFTER REMOVAL OF CARBOXYL GROUPS FROM A DIDICARBOXYLIC ACID HAVING A MOLECULAR WEIGHT LESS THAN ABOUT 300 AND D IS A DIVALENT RADICAL REMAINIG AFTER REMOVAL OF HYDROXYL GROUPS FROM A DIOL HAVING A MOLECULAR WEIGHT LESS THAN ABOUT 250; PROVIDED SAID SHORT CHAIN ESTER UNITS AMOUNT OF ABOUT 15-95 PERCENT BY WEIGHT OF SAID COPOLYETHERESTER; SAID COPOLYETHERESTER BEING STABILIZED AGAINST THERMAL DEGRADATION BY THE INCLUSION THEREIN OF A MIXTURE OF (A) A 0.2-5 WEIGHT PERCENT OF A DIARYL AMINE AND (B) 0.1-3 WEIGHT PERCENT OF A NICKEL SALT OF A SCHIFF BASE DERIVED FROM SALICYL ALDEHYDE AND AN AROMATIC AMINE OR AMINO PYRIDINE, SAID WEIGHT PERCENTAGES BEING BASED ON THE WEIGHT PERCENT OF COPOLYETHERESTER. |
