PURPOSE: To obtain a stabilized composition that exhibits excellent stability in processing at high temperatures by making it from an organic material readily decomposable by oxidation, heat, or actinic radiation and a specified compound in effective stable amounts. n CONSTITUTION: This composition is made from an organic material (e.g. PP) readily decomposable by oxidation, heat, or actinic radiation and a compound of formula I [wherein X represents a group of one of formulae II to III (wherein R 1 and R 2 each represent H, a 1-36C alkyl, a 1-18C alkyl interrupted by a specified group, a 5-12C cycloalkyl, a 7-15C phenylalkyl, a 6-14C aryl, or the like), R 3 -R 4 each represent H, a (OH- or acetoxy-substituted) 1-9C alkyl, a 3-6C alkenyl, or a 6-10C aryl, and R 5 -R 7 each represent R 3 or the like] (e.g. o-allyl-N, N-dioctadecylhydroxylamine) in effective stable amounts. n COPYRIGHT: (C)1992,JPO |
