Synthèse, polymérisation et copolymérisation d'un dérivé 2h‐benzotriazolylphényl de l'acétate de vinyle

Abstract

1 -(4-Acetoxy)-3-(2H-benzotriazolylphenyl)vinyl acetate (4) was synthesized. The polymerization of 4 afforded polymer 5 with a relatively low molecular weight (= 2000). Copolymerizations of 4 (3,7 wt.-Vo) were carried out with styrene and methyl methacrylate to copolymers 6 and 7, respectively. Polymer 5 and copolymers 6 and 7 were characterized by I H and I3C NMR and by IR and UV spectroscopy. Their UV spectra show a strong absorption in the near UV spectrum. 4 may thus be considered as a potential comonomer for UV protection.
