  • Process for preparing particles of polyphenylene sulfide polymer
    Patent number: 11905364
    Abstract: A process for preparing particles of polyphenylene sulfide polymer (PPS), based on the use of a polyester polymer (PE) comprising units from a dicarboxylic acid component and a diol component, wherein at least 2 mol. % of the diol component is a poly(alkylene glycol). The process comprises the melt-blending of the PPS with the PE, the cooling the blend and the recovery of the particles by dissolution of the PE into water. The present invention relates to PPS particles obtained therefrom and to the use of these particles in SLS 3D printing, coatings and toughening of thermoset resins.
    Type: Grant

  • Polyphenylene fibers and corresponding fabrication methods
    Publication number: 20170349699
    Abstract: Described herein are polyphenylene fibers. The polyphenylene fibers have one or more polyphenylene polymers. The polyphenylene fibers can further include one or more poly(aryl ether sulfone) polymers. In some embodiments, the polyphenylene fibers can have an average diameter that is less than about 1 micron. The polyphenylene fibers can have desirable mechanical properties. Also described herein are methods for forming polyphenylene fibers. In some embodiments, the fibers can be fabricated using specifically engineered polymer solutions in conjunctions with adapted force spinning techniques.
