Abstract: Compounds which contain peroxide linkages as well as a hindered amine light stabilizer moiety of low basicity function as free radical polymerization initiators and provide a polymer containing a hindered amine stabilizer chemically bonded to said polymer. The low basicity of the instant compounds prevents interaction with acid catalysts used in some polymerization systems.

Abstract: 5-alpha-Cumyl-2-(2-hydroxy-3,5-di-tert-butylphenyl)-2H-benzotriazole and related 2H-benzotriazoles substituted on the benzo ring by at least one aralkyl group such as benzyl, alpha-methylbenzyl or alpha-cumyl exhibit outstanding efficacy in protecting organic substrates from light-induced deterioration as well as good resistance to loss by volatilization or exudation during the high temperature processing of stabilized compositions. The above-named compounds are surprisingly soluble in common organic solvents, and exhibit very high extinction coefficients.
