HIGH MOLECULAR WEIGHT NONPOLAR BENZOTRIAZOLES

摘要

The present invention relates to the use of certain benzotriazole derivatives of the general formula (I) where B is an optionally substituted 2-(2-hydroxyphenyl)-2H-benzotriazole group, n is an integer from the range from 3 to 20 and A is an n-valent organic radical, as UV absorber or stabilizer in inanimate organic materials. Furthermore, the invention relates to methods of stabilizing inanimate organic materials, in particular plastics, against the effect of light using specific benzotriazole derivatives. Further subject matters of the invention are certain benzotriazole derivatives and inanimate organic materials comprising certain benzotriazole derivatives.
