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 […]
