(FR) COMPOSES DE 2,2'-BIS(6-BENZOTRIAZOLYLPHENOL), ABSORBEURS UV LES COMPRENANT, COPOLYMERES LES CONTENANT ET COMPOSITIONS POLYMERES LES CONTENANT
Abstract:
(EN) New 2,2'-bis(6-benzotriazolylphenol) compounds of general formula (1), wherein A represents methylene or the like; R1 and R5 each represents hydrogen, alkyl or the like; R2 represents hydrogen or the like; R3 represents alkylene or the like; and R4 represents hydrogen or methyl. These compounds are useful as ultraviolet absorbers. These compounds can be copolymerized with a vinyl monomer to form copolymers. Polymer compositions containing the copolymers are usable as ultraviolet absorbers.
(FR) L'invention concerne de nouveaux composés de 2,2'-bis(6-benzotriazolylphénol) de la formule générale (I) dans laquelle A représente méthylène ou analogue; R1 et R5 représentent chacun hydrogène, alkyle ou analogue; R2 représente hydrogène ou analogue; R3 représente alkylène ou analogue; et R4 représente hydrogène ou méthyle. Ces composés sont utiles en tant qu'absorbeurs UV. Ces composés peuvent être copolymérisés avec un monomère vinylique pour former des copolymères. Des compositions copolymères contenant les copolymères sont utilisables en tant qu'absorbeurs UV.
