Abstract
N-(Hydroxyalkoxy) hindered amine stabilizers are prepared by reacting the corresponding N-oxyl compound with a peroxide or organic hydroperoxide and a catalytic amount of a metal salt or metal-ligand complex in an alcohol solvent. These N-(hydroxyalkoxy) hindered amines are particularly useful as stabilizers for polyolefins, thermoplastic polyolefins and automotive coating compositions.
