Sterically hindered N-hydrocarbyloxyamines are prepared from hindered amine N-oxyl compounds by a process which uses hydrogen peroxide or a hydrogen peroxide equivalent, a catalytic amount of a peroxide decomposing transition metal salt, metal oxide, or metal-ligand complex, a hydrocarbon solvent containing no activated hydrogen atoms, and a relatively inert cosolvent. These compounds are useful as thermal and light stabilizers for a variety of organic substrates.

1-Hydrocarbyloxy substituted hindered amine compounds which also contain a reactive functional group such as hydroxy, amino, oxirane or carboxyl can be chemically attached to selected polymer substrates by condensation reactions to give polymers containing a chemically-bonded, non-migrating stabilizer having excellent stabilization efficacy for protecting said polymer substrate from the adverse effects of actinic light.
Poly(1-hydrocarbyloxy-2,2,6,6-tetraalkylpiperidine) compounds are effective light stabilizers in protecting organic polymers against the deleterious effects of actinic light.
