Compounds containing both uv-absorber and 1-hydrocarbyloxy hindered amine moieties and stabilized compositions

Abstract From the Canadian patent

Compounds containing both a UV-absorbing moiety and a 1-hydrocarbyloxy hindered amine moiety are effective stabilizers for protecting polymer compositions against the deleterious effects of actinic light. The UV-absorbing moieties include the substituted 2H-benzotriazoles s-triazines, acrylates, benzophenones, oxanilides and oxamides. The compounds have one of the formulas I to VI (see above formulas), (see above formulas) wherein, R1 is hydrogen, halogen, alkyl of 1 to 12 carbon atoms or aralkyl of 7 to 15 carbon atoms, wherein R1 is a group such as C1-C12 alkyl, R and R2 are independently groups such as H and C1-C12 alkyl, R3 and R4 are independently groups such as C1-C4 alkyl X is a …
