A-17703/+/CGC 1442 POLYMER STABILIZERS CONTAINING BOTH HINDERED AMINE AND NITRONE MOIETIES Compounds possessing both a hindered amine moiety, such as a derivative of 2,2,6,6-tetramethylpiperidine, and a nitrone moiety are valuable stabilizers for protecting polymer compositions against the deleterious effects of actinic light and from the adverse effects of high temperature polymer processing environments. Additionally, the instant compounds present the opportunity for grafting onto performed polymer backbones.
