  • Patent number: 7582690
    Abstract: 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.

  • Publication number: 20080167440
    Abstract: comonomers have been shown to improve flammability characteristics of polyesters and copolyesters. Incorporation of sulfonate containing monomers such as 5-sodiosulfoisophthalic acid significantly decreases the heat release capacity of copolyesters. These comonomers also increase the formation of char as measured by thermogravimetric analysis. The decrease in the heat release capacity and increase in char formation indicates that these compositions may have reduced flammability and thus are useful for producing products have reduced flammability. In particular, it has also been demonstrated that incorporation of as little as 0.1 mole % 5-sodiosulfoisophthalic acid to a polyester or copolyester significantly increases the char formation independent of composition.

  • Patent number: 7157547
    Abstract: An ultraviolet absorption composition has been developed for the protection of packaging or container contents in the ultraviolet range of 290 nm to 390 nm, offering effective screening from all wavelengths of solar radiation. A combination of an optical brightener with an ultraviolet absorber has been found to provide effective screening without adding significant color to the polymer composition. This extended range of ultraviolet blocking over what can be achieved with ultraviolet absorbers alone is especially valuable in food and drink packaging applications where the contents of the packages need ultraviolet protection to prevent discoloration or development of undesirable flavors.
