    • The invention relates to multichromophoric compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing a stabilizing amount of the multichromophoric composition to prevent such degradation. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including, for example, pigments, colorants, fillers, reinforcing agents and the like. These ultraviolet stabilizers may also be incorporated into the organic compositions in the polymer melt or dissolved in the polymer dope, coated on the exterior of the molded article, film or extruded fiber.
    • 本发明涉及已被发现是有效的紫外线稳定剂的多色素化合物。 本发明还涉及含有稳定量的多色母体组合物以防止这种降解的紫外可降解有机组合物。 这些稳定剂在通常用于聚合物组合物中的其它添加剂的存在下是有效的,包括例如颜料,着色剂,填料,增强剂等。 这些紫外线稳定剂也可以掺入聚合物熔体中的有机组合物中或溶解在聚合物涂料中,涂覆在模塑制品,薄膜或挤出纤维的外部上。

    • Disclosed are polyester substrates or sheets laminated with an acrylic film and having exceptionally improved resistance to surface deterioration on weathering. These laminates are especially suited for use in applications such as windows, signs, solar collectors, green house covers and the like which are subject to extended periods of outdoor exposure. Typical polyesters include modified poly(ethylene terephthalate), and modified poly(1,4-cyclohexylenedimethylene terephthalate) such as those of terephthalic acid with ethylene glycol and 1,4-cyclohexanedimethanol, e.g., poly(69/31 molar-ethylene/1,4-cyclohexylenedimethylene terephthalate) and poly(65/35 molar-1,4-cyclohexylenedimethylene/ethylene terephthalate). The acrylic polymer films suitable forlamination to the polyester sheeting are homopolymers and copolymers prepared from either or both of the monomers H.sub.2 C.dbd.CHCO.sub.2 R and H.sub.2 C.dbd.C(CH.sub.3)CO.sub.2 R.sup.1 wherein R and R.sup.1 are each selected from C.sub.1 -C.sub.12 linear or branched alkyl groups.
