  • Publication number: 20070071930
    Abstract: Disclosed are oriented, shaped articles such as, for example, film, fibers, bottles, and tubes, with excellent strength, toughness, clarity, chemical resistance, and UV resistance. The articles can be prepared from cycloaliphatic polyesters and from compositions comprising cycloaliphatic polyesters and cycloaliphatic polyester elastomers. The articles may be oriented by stretching in at least one direction and have a modulus which results in a soft feel. Also disclosed are polyester compositions comprising cycloaliphatic polyesters and polyester elastomers.
