Patent number: 10501626Abstract: Polyarylene sulfide compositions are described that exhibit high strength and flexibility. Methods for forming the polyarylene sulfide compositions are also described. Formation methods include dynamic vulcanization of a polyarylene sulfide composition that includes an impact modifier dispersed throughout the polyarylene sulfide. A crosslinking agent is combined with the other components of the composition following dispersal of the impact modifier throughout the composition. The crosslinking agent reacts with the impact modifier to form crosslinks within and among the polymer chains of the impact modifier. The compositions can exhibit excellent physical characteristics at extreme temperatures and can be used to form, e.g., tubular member such as pipes and hoses and fibers.Type: GrantFiled: November 14, 2016Date of Patent: December 10, 2019Assignee: Ticona LLCInventors: Rong Luo, Joseph J.

Patent number: 9353263Abstract: A thermoplastic composition for use in a fine pitch electrical connector is provided. The thermoplastic composition contains a liquid crystalline polymer and a plurality of fibers. The volume average length of the fibers in the thermoplastic composition is selectively controlled according to the present invention so that it is within a certain range, such as from about 80 to about 250 micrometers. The fibers also have a narrow length distribution. That is, at least about 70% by volume of the fibers have a length within a certain range. Through the use of a liquid crystalline polymer and fibers of a certain weight average length and narrow length distribution, the present inventors have discovered that the resulting thermoplastic composition is able to achieve a desirable combination of strength and flowability, which enables it to be uniquely suited for the walls of a fine pitch connector.Type: GrantFiled: November 13, 2012Date of Patent: May 31, 2016Assignee: Ticona LLCInventors: Young Shin Kim, Xinyu Zhao, Joseph J.

Patent number: 9102792Abstract: A polymer composition that contains at least one high performance polymer and at least one aromatic amide oligomer is provided. The oligomer can serve as a flow aid that lowers the overall viscosity of the polymer matrix under shear.Type: GrantFiled: February 19, 2014Date of Patent: August 11, 2015Assignee: Ticona LLCInventors: Kamlesh P.

Patent number: 9096794Abstract: A liquid crystalline polymer composition that contains a liquid crystalline polymer and an aromatic amide oligomer is provided. The oligomer can serve as a flow aid by altering intermolecular polymer chain interactions, thereby lowering the overall viscosity of the polymer matrix under shear. The oligomer is also not easily volatized or decomposed during compounding, molding, and/or use, which minimizes off-gassing and the formation of blisters that would otherwise impact the final mechanical properties of a part made from the polymer composition. While providing the benefits noted, the aromatic amide oligomer does not generally react with the polymer backbone of the liquid crystalline polymer to any appreciable extent so that the mechanical properties of the polymer are not adversely impacted.Type: GrantFiled: August 27, 2012Date of Patent: August 4, 2015Assignee: Ticona LLCInventors: Kamlesh P.

Patent number: 9045685Abstract: A molded part having a predetermined shape is provided. The molded part may be formed by casting a liquid crystalline polymer composition into a mold cavity at a relatively low shear rate. Due to the use of a relatively low shear rate, the polymer composition does not generally undergo extensive shear orientation, which can allow the resulting part to be further processed using standard finishing techniques. The ability to use relatively low shear rates during casting is achieved in the present invention through the use of an aromatic amide oligomer. More particularly, the present inventors have discovered that the aromatic amide oligomer can serve as a flow aid by altering intermolecular polymer chain interactions, thereby lowering the overall viscosity of the polymer matrix to “ultralow” levels without having a significant impact on the mechanical properties.Type: GrantFiled: August 27, 2012Date of Patent: June 2, 2015Assignee: Ticona LLCInventors: Kamlesh P. Nair, Steven D. Gray, Joseph J. Grenci

Patent number: 8906258Abstract: 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.Type: GrantFiled: August 27, 2012Date of Patent: December 9, 2014Assignee: Ticona LLCInventors: Steven D. Gray, Kamlesh P. Nair, Joseph J. Grenci

Publication number: 20140242385Abstract: 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.Type: ApplicationFiled: February 19, 2014Publication date: August 28, 2014Applicant: Ticona LLCInventors: Kamlesh P.
