Zusammenfassung:	BENZOATES ET PHENULSULFONATES DE PHENYLE A FONCTION SILANE PRECURSEUR DE FILTRE U.V., COMPOSITIONS OBTENUES ET PRODUITS REVETUS DE CES COMPOSITIONS.PRECURSEURS NON MIGRANTS ET NON PLASTIFIANTS.ILS REPONDENT AUX FORMULES:(CF DESSIN DANS BOPI)R REPRESENTE UN GROUPE ALKYLE EN C A C, R REPRESENTE UN GROUPE ALKYLE EN C A C OU UN GROUPE ALCANOYLE EN C A C, R REPRESENTE L'HYDROGENE OU UN GROUPE ALCOXY EN C A C, X EST EGAL A 0, 1 OU 2, Y EST EGAL A 1, 2 OU 3 ET XY3. APPLICATION AUX POLYCARBONATES. Silane-functionalized ultraviolet screening agent precursors comprise compounds of the formula: +TR wherein R is R1 is C1-C6 alkyl, R2 is C1-C6 alkyl or C2-C6 alkanoyl, R3 is hydrogen or C1-C6 alkoxyl, X is 0,1 or 2, y is 1,2, or 3 and x+y=3. Under ultraviolet radiation the compounds rearrange to the corresponding alpha -hydroxybenzophenones which protect substrates, especially transparent plastics, against degradation.
