Polysubstituted n-hydrocarbyloxy hindered amine light stabilizers

Claim 1

A polysubstituted N-hydrocarbyloxy compound of the formula ##STR8## where n is 2 to 10, R 1 and R 2 are independently alkyl of 1 to 4 carbon atoms, or R 1 and R 2 together are pentamethylene, L is an n-valent radical of an alkane or alkene of 1 to 18 carbon atoms, an n-valent radical of a cycloalkane or cycloalkene of 5 to 12 carbon atoms, an n-valent radical of a bicyclic or tricyclic hydrocarbon of 7 to 12 carbon atoms or an n-valent radical of an aryl, alkyl substituted aryl or aralkyl hydrocarbon of 6 to 15 carbon atoms, with the proviso that the N--O groups are not necessarily attached to the same carbon atom in L, T is an organic moiety selected from the group consisting of E--COO--, E 1 --OCO--, E--CONR 3 -- ##STR9## E 1 NHCOCONH--, ##STR10## E 1 OCO(CH 2 ) m NH--, E 1 OCO(CH 2 )pCOO--, ##STR11## where E is phenyl, vinyl or alkyl of 1 to 17 carbon atoms, E 1 is methyl or ethyl, R 3 is hydrogen, alkyl of 1 to 8 carbon atoms or ##STR12## where L 1 is a monovalent radical of the definition of L, m is 2 to 4, p is 0 to 10, G is hydrogen or alkyl of 1 to 18 carbon atoms, and X is hydrogen or --CH 2 CH 2 COOC 12 H 25 .
