    Abstract: A boron-containing nucleating agent is provided for use with a polyarylene sulfide. The boron-containing nucleating agent can have low crystallinity, a small particle size, and a large specific surface area. By selectively controlling certain aspects of the nucleating agent, the crystallization properties of a thermoplastic composition including the nucleating agent and a polyarylene sulfide can be significantly improved. For instance, the recrystallization temperature can be increased, which can allow the “cooling time” during a molding cycle to be substantially reduced. Through use of the boron-containing nucleating agent the recrystallization temperature can be greater than about 231° C.

  • Patent number: 9018336
    Abstract: A polymer of sulfonated poly(arylene ether)s (PAEs) and a manufacturing method thereof are provided. A main structure of the PAEs has a first side formed by multi-phenyl glycol monomer and a second side formed by multi-phenyl dihalo monomer with an electron-withdrawing group. The glycol monomer and the dihalo monomer are reacted with each other by a nucleophilic displacement reaction, so as to form the main structure of the PAEs. A film made of the PAEs has a better size stability under a high water uptake.

  • Publication number: 20150030784
    Abstract: In a conductive film forming method using photo sintering, a conductive film having low electric resistance is easily formed. The conductive film forming method is a method in which a conductive film is formed using photo sintering. This method includes the steps of forming a layer made of a sintering promoter on a substrate, forming a liquid film made of a copper particulate dispersion on the layer of the sintering promoter, drying the liquid film to form a copper particulate layer, and subjecting the copper particulate layer to photo sintering. The sintering promoter is a compound which removes copper oxide from metallic copper. Thereby, the sintering promoter removes a surface oxide film of copper particulates in photo sintering.
