  • Publication number: 20150112019
    Abstract: A thermoplastic composition that comprises a low-naphthenic, thermotropic liquid crystalline polymer blended with a combination of flow modifiers is provided. More particularly, one of the flow modifiers is a hydroxy-functional compound that contains or more hydroxyl functional groups. Without intending to be limited by theory, it is believed that the hydroxyl functional groups can react with the polymer chain to shorten its length and thus reduce melt viscosity. Aromatic dicarboxylic acids are also employed as a flow modifier in the thermoplastic composition. Again, without intending to be limited by theory, it is believed that such acids can combine smaller chains of the polymer together after they have been cut by hydroxy-functional compounds. This helps maintain the mechanical properties of the composition even after its melt viscosity has been reduced.

    Abstract: The present invention appreciates that compounds comprising ester linkages and nitrogen-containing moieties that are at least divalent (e.g., urea, urethane, amide, etc.) can be crosslinked with azides to form membranes that are resistant to C02 plasticization, that are selective for acid gases relative to nonpolar gases such as hydrocarbons, and that have high acid gas flux characteristics. The resultant membranes have stable structure and stable separation properties at higher temperatures and pressures. The membranes are compatible with many industrial processes in which polar gases are separated from nopolar gases. In an exemplary mode of practice, the membranes can be used to separate acid gases from the hydrocarbon gases in natural or non-acid gas components of flue gas mixtures (e.g., N2, O2, etc.).

    Abstract: Copolyetherester compositions comprising a melt-mixed blend of one or more copolyetherester(s) comprising a multiplicity of recurring long chain ester units and short chain ester units joined head-to-tail through ester linkages, and (b) about 0.25 to about 15 weight percent of one or more polyhydric alcohols having more than two hydroxyl groups; wherein all weight percentages are based on the total weight of the copolyetherester composition. Molded or extruded thermoplastic articles formed from the copolyetherester compositions, wherein 2 mm test bars prepared from said copolyetherester composition, and exposed at a test temperature of 150° C. for a test period of about 120 hours, in an atmosphere of air, and tested according to according to ISO 527-2/5A method have, on average, a retention of tensile strain at break of at least 50 percent as compared with an unexposed control having identical composition and shape.

  • Patent number: 8188185
    Abstract: A biodegradable packaging film is provided. The film is formed from a blend that contains a thermoplastic starch and polylactic acid. Starch is a relatively inexpensive natural polymer that is also renewable and biodegradable. Polylactic acid is likewise an inexpensive synthetic polymer that is biodegradable and renewable, yet also capable of providing increased tensile strength to the film. Although providing a good combination of biodegradability/renewability and increased tensile strength, the polylactic acid is also relatively rigid and can result in films having a relatively high stiffness (e.g., high modulus of elasticity) and low ductility. While more ductile than polylactic acid, the thermoplastic starch is often difficult to melt process in film forming processes and very sensitive to moisture and water vapor, reducing its ability to be used as a stand alone packaging film.
