RUVA 93

2-Propenoic acid, 2-methyl-, 2-[3-(2H-benzotriazol-2-yl)-4-hydroxyphenyl]ethyl ester

RUVA-93 copolymerizes efficiently with a variety of monomers, such as methacrylic, styrenic, and acrylonitrile monomers, thus providing permanent placement of the benzotrizole in the polymer. The advantages associated with a UV stabilizer bonded to a polymer backbone over the typical “additive” stabilizers include the permanence of the stabilizer in the resin, improved compatibility even in the very high loadings, excellent environmental acceptability, expanded technology options and ability to design new UV polymer screens with unique properties.
