Abstract

Certain sterically hindered hydroxy-substituted hydrocarbyloxyamine stabilizers are found to be especially efficacious towards stabilizing organic material subject to degradation induced by light, heat or oxidation. Disclosed are stabilized compositions comprising (a) an organic material subject to degradation induced by light, heat or oxidation and (b) one or more sterically hindered hydroxy-substituted hydrocarbyloxyamine stabilizers, said stabilizers selected from the group consisting of 1.) 1-(2-hydroxy-2-methylpropoxy)-4-hexadecanoyloxy-2,2,6,6-tetra-methyl-piperidine, 2.) the reaction product of 1-oxyl-4-hydroxy-2,2,6,6-tetramethylpiperidine with a carbon radical from t-amylalcohol, 3.) 1-(2-hydroxy-2-methylpropoxy)-4-hydroxy-2,2,6,6-tetra-methyl-piperidine, 4.) 1-(2-hydroxy-2-methylpropoxy)-4-oxo-2,2,6,6-tetra-methyl-piperidine, 5.) 1-(2-hydroxy-2-methylpropoxy)-4-octadecanoyloxy-2,2,6,6-tetra-methyl-piperidine 6.) bis(1-(2-hydroxy-2-methylpropoxy)-2,2,6,6-tetra-methyl-piperidin-4-yl) sebacate, 7.) bis(1-(2-hydroxy-2-methylpropoxy)-2,2,6,6-tetra-methyl-piperidin-4-yl) adipate, 8.) bis(1-(2-hydroxy-2-methylpropoxy)-2,2,6,6-tetra-methyl-piperidin-4-yl) succinate, 9.) bis(1-(2-hydroxy-2-methylpropoxy)-2,2,6,6-tetra-methyl-piperidin-4-yl) glutarate and 10.) 2,4-bis{N-[1-(2-hydroxy-2-methyl-propoxy)-2,2,6,6-tetra-methyl-piperidin-4-yl]-N-butyl-amino}-6-(2-hydroxy-ethyl-amino)-s-triazine.
