摘要：

The reactivity of 2(2-hydroxy-5-vinyl)2H-benzotriazole (2H5V) structural units in a copolymer with methyl methacrylate (MMA) with respect to alkyl or peroxy radicals in the solid phase was studied. Alkyl radicals were generated through mechanical degradation of the copolymer and peroxy radicals were obtained by oxidation of alkyl radicals. Formation of oxy radicals expected in 2H5V-MMA copolymer was not observed even in the presence of alkyl or peroxy radicals. The resistance of 2H5V structural units of a copolymer to both types of radicals is attributed to the stability of the structure of 2H5V which is probably assisted by hydrogen bonding.
