    摘要: Disclosed are stabilized aliphatic polyester compositions comprising an aliphatic polyester, a HALS, and a tris-aryl-S-triazine UV absorber that show low embrittlement, haze formation, and discoloration during weathering. Also disclosed are aliphatic polyester compositions comprising aliphatic polyester, a hindered amine light stabilizer, a triazine UV absorber, and a phosphite that exhibit low color prior to weathering but retain good clarity, color, and excellent impact strength after exposure to weathering conditions. The aliphatic polyester compositions may be used prepare shaped articles such as, for example, films, sheets, bottles, tubes, profiles, fibers, and molded articles.

    摘要: Optical brighteners are widely used for decreasing the apparent yellowness of polymeric materials. Polyethylene, as a coating film for photographic paper has presented unique problems because of its general lack of compatibility with conventional, large, fluorescent brightener molecules. The present invention provides a solution to this problem by incorporating into the polyethylene an optical brightener compatibilizing amount of a second polyolefin having alkyl groups pendant from the polymer backbone which serves to reduce the exudation of the optical brightener in articles or substrates comprised of or coated with such compositions.

    摘要: Provided is a process for alkylating aromatic compounds in the presence of mixed oxides of titanium and gallium which have been found to be highly active catalysts for the alkylation of aromatics with alkyl esters, alcohols, olefins and ethers. When the alkyl acceptor is a phenol, the catalysts provide high reaction rates and high selectivity for ortho alkylated products.

    摘要: The invention relates to heterocyclic ester compounds which have been found to be extremely effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing an amount of a heterocyclic ester 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 such as polymers by adding to the polymer melt or dissolved in the polymer dope, coated on the exterior of the shaped or molded article, film or extruded fiber.
