The melting temperature may, for example, range from about 250° C. to about 400° C. Even at such low melting temperatures, the present inventors have surprisingly discovered that the ratio of the deflection temperature under load (“DTUL”), a measure of short term heat resistance, to the melting temperature may remain relatively high. The specific DTUL values may range from about 200° C. to about 300° C.

  • Publication number: 20140242385
    Abstract: A fiber formed from a polymer composition that comprises a liquid crystalline polymer and an aromatic amide oligomer is provided. The present inventors have discovered that the oligomer can act as a flow aid for the polymer, which can provide a variety of different benefits. For example, the use of the oligomer during polymerization can lower the melt viscosity of the polymer as it is formed. This enables the formation of high molecular weight polymers that do not solidify within the reactor vessel. The formation of high molecular weight polymers during melt polymerization can, in turn, provide a variety of benefits, such as allowing for higher molecular weight polymers to be formed through additional processing (e.g., solid state polymerization) than conventionally possible, as well as enhancing the melt strength of the polymer composition and thereby aiding in the fiber formation process.

    Abstract: A method for forming a high molecular weight thermotropic liquid crystalline polymer is provided. The method includes melt polymerizing two or more monomers in the presence of a unique aromatic amide oligomer to form a prepolymer, and then solid-state polymerizing the prepolymer to achieve a target molecular weight. The present inventors have discovered that a unique aromatic amide oligomer can be employed to help increase the “low shear” complex viscosity of the resulting solid-state polymerized composition. This allows for the attainment of higher than conventional “low shear” complex viscosity values and/or a substantial reduction in the solid-state polymerization time needed to achieve a target complex viscosity. In addition, the oligomeric flow aid can also accelerate the extent to which the “high shear” melt viscosity is increased during solid-state polymerization, which may also contribute to a substantial reduction in the solid-state polymerization time needed to achieve a certain molecular weight.

  • Patent number: 8575296
    Abstract: A polyester article is made to appear lustrously metallic or pearlescent by the addition of polymethylpentene and non-metallic, non-pearlescent colorant; and optionally other functional additives. The colorant can be one or more pigments, one or more dyes, or combination thereof. A stretch blow molded plastic article, such as a bottle, using the polymethylpentene in the polyester can simulate the appearance of a metallic surface or a pearlescent luster even though non-metallic and non-pearlescent colorants are used.

  • Patent number: 8524855
    Abstract: Environmentally-friendly, biodegradable polyol:carboxylic acid polyester solid-phase products may be produced utilizing microwave heating. In this process, a di- or tricarboxylic acid is reacted with a polyol such as a glycerol or a sugar alcohol, or an ester thereof with the application of heating by microwave energy. Sufficient microwave heating is provided to esterify the polyol with the carboxylic acids, while removing as steam the water by-product which is generated during the reaction. The polyesters so-produced are resistant to high temperatures and solvents, and may by cured and/or molded.

  • Publication number: 20130048908
    Abstract: A thermotropic liquid crystalline polymer composition capable of exhibiting both a low melting temperature and good heat resistance without the use of conventional naphthenic acids is provided. The melting temperature may, for example, range from about 250° C. to about 400° C. Even at such low melting temperatures, the present inventors have surprisingly discovered that the ratio of the deflection temperature under load (“DTUL”), a measure of short term heat resistance, to the melting temperature may remain relatively high. The specific DTUL values may range from about 200° C. to about 300° C. The ability to form a polymer composition with the properties noted above may be achieved, at least in part, by the use of an aromatic amide oligomer.
