Publication number: 20130273283Abstract: Disclosed is a UV stabilized polyarylene sulfide composition, methods of forming the composition, and UV stabilized products that can be formed of the composition. The UV stabilized polyarylene sulfide composition can include a reactively functionalized polyarylene sulfide polymer in conjunction with a UV stabilizer. The reactivity of the polyarylene sulfide polymer is formed during melt processing via reaction of a reactively functionalized disulfide compound with a starting polyarylene sulfide. The reactivity of the polyarylene sulfide can encourage interaction between the polyarylene sulfide polymer and the UV stabilizer, which can improve dispersion of the UV stabilizer throughout the composition and improve miscibility between the polyarylene sulfide polymer and the UV stabilizer. Products can incorporate high concentrations of UV stabilizer and/or can be formed to very small cross sectional dimensions without phase separation between the UV stabilizer and the polyarylene sulfide.Type: ApplicationFiled: March 13, 2013Publication date: October 17, 2013Applicant: TICONA LLCInventors: Ke Feng, Rong Luo, Xinyu Zhao

Publication number: 20130273280Abstract: A continuous fiber composite is described and methods for forming the continuous fiber composite. The continuous fiber composite includes a plurality of unidirectionally aligned continuous fibers embedded within a polyarylene sulfide polymer. The continuous fiber composite includes a very high loading of continuous fibers, for instance greater than about 40% by weight of the continuous fiber composite. The continuous fiber composite is formed by reacting a starting polyarylene sulfide with a reactively functionalized disulfide compound in a melt processing unit. Reaction between the starting polyarylene sulfide and the reactively functionalized disulfide compound leads to formation of a reactively functionalized polyarylene sulfide. Upon embedding of the continuous fibers into the reactively functionalized polyarylene sulfide, the reactivity of the polyarylene sulfide can enhance adhesion between the polyarylene sulfide polymer and the fibers.Type: ApplicationFiled: March 13, 2013Publication date: October 17, 2013Applicant: TICONA LLCInventors: Rong Luo, Aaron Johnson, Tim Tibor, Xinyu Zhao, David Eastep

Publication number: 20130249357Abstract: An injection molded housing for a portable electronic device is provided. The housing contains a thermoplastic composition that includes a polyarylene sulfide melt processed in the presence of a disulfide compound and a filler. Without intending to be limited by theory, it is believed that the disulfide can undergo a chain scission reaction with the starting polyarylene sulfide to lower its melt viscosity, which can lead to decreased attrition of the filler and thus improved mechanical properties. Due to this ability to reduce viscosity during melt processing, the present inventors have discovered that relatively high molecular weight polyarylene sulfides can be fed to the extruder with little difficulty.Type: ApplicationFiled: September 18, 2012Publication date: September 26, 2013Applicant: TICONA LLCInventors: Rong Luo, Xinyu Zhao, Ke Feng

Publication number: 20130227759Abstract: A fabric that contains a blend of textile and polyarylene sulfide fibers is provided. At least a portion of the textile fibers, polyarylene sulfide fibers, or a combination thereof are coated with an emulsion copolymer that is crosslinked. The copolymer composition is cured after it is applied to the fibers to initiate the formation of crosslink bonds between the emulsion copolymer and create a three-dimensional network that is capable of coating and encapsulating the fibers. It is believed that this three-dimensional network is able to physically entrap disperse additives when applied to the fibers. Still further, the present inventors have discovered that the emulsion copolymer can uniformly coat the fibers and thus readily receive the additive, which eliminates the need for high temperatures and/or pressures during a dyeing process, for example, and can also result in a relatively uniform coating of the additive on the fibers.Type: ApplicationFiled: February 22, 2013Publication date: September 5, 2013Applicant: TICONA LLCInventors: Harrie P.

Publication number: 20130227800Abstract: A fibrous material that contains polyarylene sulfide fibers coated with an emulsion copolymer is provided. The emulsion copolymer that is coated onto the polyarylene sulfide fibers is crosslinked. For example, the copolymer may contain a reactive co-monomer that acts as a crosslinking agent. Alternatively, a separate crosslinking agent may be combined with the emulsion copolymer. In either case, the resulting copolymer composition is cured after it is applied to the fibers to initiate the formation of crosslink bonds between the emulsion copolymer and create a three-dimensional network that is capable of coating and encapsulating the fibers. Without intending to be limited by theory, it is believed that this three-dimensional network is able to physically entrap disperse dyes when applied to the fibers.Type: ApplicationFiled: February 22, 2013Publication date: September 5, 2013Applicant: Ticona LLCInventors: Harrie P.

The stabilizer comprises a phosphite stabilizer. The composition produces molded articles having better thermal stability and reduced mold deposits.Type: ApplicationFiled: May 21, 2010Publication date: April 11, 2013Inventors: Xinyu Zhao, Ke Feng

Publication number: 20130081850Abstract: A conduit that contains an elongate member that defines a hollow passageway is provided.

Regardless of the type of conduit, at least a portion of the elongate member is formed from a thermoplastic composition that contains a polyarylene sulfide and fire-resisting system. Due in part to the specific nature and concentration of these components, the present inventors have discovered that the resulting thermoplastic composition may have a relatively high melting temperature.Type: ApplicationFiled: September 4, 2012Publication date: April 4, 2013Applicant: TICONA LLCInventors: Christopher McGrady, Kaushik Chakrabarty, David McIlroy, Xinyu Zhao
