Functional polymers - 65. synthesis and brief characterization of surface active 2(2-hydroxyphenyl)2H-benzotriazole ultraviolet stabilizers

A number of 2(2-hydroxyphenyl)2H-benzokiazoles substituted in the 5-positio n with reactive hydroxyl and carboxyl groups have been synthesized. They in clude compounds with a tert butyl substitution in the 3-position or without substitution. The latter compounds were subjected to a reaction with N-hyd roxymethyl-(meth)acrylamide to form acrylic polymerizable 3(meth) acrylamid omethyl-2(2-hydroxyphenyl)2H-benzotriaz-oles. Hydroxyl reactive compounds w ere allowed to react with long chain acids, compounds with carboxyl groups with long chain hydrocarbon, fluorocarbon or silicon oligomer alcohols. The polymerizable 2(2-hydroxyphenyl)2H-benzotriazoles were then copolymerized with methyl methacrylate. Films made from such polymers showed by contact a ngle measurements, substantial migration of the fluorocarbon or silicon com ponent to the surface of the film.
