Abstract: Disclosed are polyester blends that provide improved stress whitening behavior. The blends may be prepared from a polyester having crystallization half-time of at least 5 minutes and a polyester elastomer. The polyesters blends may be extruded or, in the presence of a release additive, calendered to produce film or sheet. Also disclosed are processes for making a film or sheet by extrusion or calendering the above blends and the film or sheet produced therefrom. The polyester blend and the film or sheet produced therefrom also may include plasticizers and/or flame retardants to increase their flexibility and enable their use in commercial applications requiring flame resistance. The film and sheet have excellent appearance and can be used in a wide range of decorative and packaging applications.

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.

Abstract: Disclosed are high clarity films produced from semicrystalline polyesters by calendering. These films unexpectedly develop a higher peak melting point, which leads to higher thermal resistance. The semicrystalline polyesters may be biodegradable. When these calendered films are oriented, they develop unexpectedly high physical strength or clarity in comparison to films that are prepared by conventional techniques.

Also disclosed are processes for flame retardant films or sheets by calendering the above compositions and the flame retardant films or sheets produced therefrom. These films and sheets have excellent appearance, flexibility, and flame retardancy, and can be used in a wide range of decorative and packaging applications.
