Abstract
The compounds 2'-hydroxy-5'-(hydroxyalkyl)phenyl-2H-benzotriazoles are useful as intermediate alcohols in the preparation of corresponding 2'-hydroxy-5'-acrylyloxyphenyl-2H-benzotriazole monomers, which in turn are copolymerizable with ethylenically unsaturated monomers, particularly acrylic monomers, to impart ultraviolet absorbing properties to the resulting copolymers.
