Summary
The absorption spectra of 2(2-hydroxyphenyl)2H-benzotriazoles derivatives substituted with electron-donating and withdrawing groups in various positions on the phenyl ring allowed to estimate the relative stability of the hydrogen-bonded structures as evidenced by the ɛ 340 nm/ɛ300 nm ratio.
Photodegradation studies of poly-cis-1,4-butadiene-1,3 with and without 2(2-hydroxyphenyl) benzotriazole absorbers with various substituents show that compounds with R=H are better photostabilizers than those with R≠H.
