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. The hindered amine compounds have one of the formulae I, II, III, IV and V: (see formula I, II and III) (see formula IV and V) wherein G1 and G2 are groups such as methyl; E is a group such as C1-C18 alkyl; T is a direct bond or a group such as -CO(CH2)m- in which m is 2 or 3; G is a group such as C2-C12 alkylene; T3 is a group such as -NH-; L may be (see formula VI) L1 may be a p-valent radical of a C1-C18 alkane; L2 may be residue of a monosaccharide; T1 may be -OH; T2 may be -OCH2CHOHCH2- n is 1 to 4 k is 1 to 100; and p is 2 to 10.
