Functional Polymers. 61. Ultraviolet Spectral Behavior of Selected 2(2-Hydroxyphenyl)2H-Benzotriazoles

Abstract Ultraviolet spectra of a number of 2(2-hydroxyphenyl)2H-benzotriazoles were studied in nonpolar, polar, and hydrogen bonding solvents. The effect of substituents located in the 4-position of the benzotriazole ring was investigated, and the effect on the UV absorption characteristics of 2(2-hydroxyphenyl)2H-benzotriazoles was determined. Substituted resorcinol or phloroglucinol-based 2(2-hydroxyphenyl)2H-benzotriazole derivatives were investigated with special emphasis on UV absorption characteristics that were expected to be useful as polymerbound UV stabilizers in optical lens applications.
