摘要：
Compounds possessing both a hindered amine moiety, such as a derivative of 2,2,6,6-tetramethylpiperidine, and a hydroxylamine moiety where the N-hydroxy group is not attached to a nitrogen atom in a piperidine ring 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.
