摘要:
A composition comprising a stabilizer chemically bonded to a polymer matrix, and which reduces the deleterious effect of UV light absorption by the polymer is provided. The stabilizer comprises a sulfur-containing derivative of hydroxyphenylbenzotriazole having the formula of: ##STR1## wherein each X is selected from the group consisting of hydrogen, halogens, cyano, alkyl, phenyl group, biphenyl group, arylthio, amine, ketone, aldehyde, alkoxy, hydroxy, carboxylic acid group, oligomer and combinations thereof and can have carbon atoms up to about 20; n is a whole number from 1 to 5; n' is a whole number from 0 to 4; n" is a wbole number from 1 to 2 and each n" can be the same or different; Y is selected from the group consisting of --S(O)(O)--, --S(O)--, and --S--; each R can be selected from the group consisting of hydrogen, alkyl group, alkenyl group, aralkyl group, alkaryl group, and combinations thereof and can have 0 to about 10 carbon atoms; each OH group can be at either the 2'- or the 6'-position, or both.
