    摘要: A method for producing an electrically conducting melt-processible fluoropolymer comprising pulverizing a composition of (a) carbon aggregate and (b) coagulum particles of aqueous dispersion polymerized melt-processible fluoropolymer, coating the coagulum particle with the disintegrated particles of carbon black. The preferred composition comprises a structured carbon black such as acetylene black and a melt processible fluoropolymer wherein said melt processible fluoropolymer has two crystallization peaks in a DSC cooling curve when allowed to crystallize from a temperature of not less than its melting point at a cooling rate of 12° C./min; and the ratio of the crystallization peak heights (high temperature side peak/low temperature side peak) is 0.65 or greater; and/or the ratio of the high temperature side crystallization peak area to the total area of the crystallization peaks [high temperature side peak area/(high temperature side peak area+low temperature side peak area)] is 0.18 or greater.

    摘要: This invention provides a tetrafluoroethylene (TFE) copolymer resin powder composition capable, upon rotational lining, of generating a corrosion-resistant, nonstick film, which is a thick film on a metal or a like substrate, essentially free of gas bubbles, and excellent in adhesion and peel resistance. The TFE-copolymer resin powder composition comprises granules which comprise particles of a TFE/perfluoro(alkyl vinyl ether) copolymer (PFA), polyphenylene sulfide (PPS) particles having an average particle size of 0.3-50 .mu.m, and a heat resistant filler. This invention also provides a process for manufacturing the TFE copolymer resin powder composition comprising either (1) granulating a mixture of PFA particles, PPS and a heat resistant filler in the presence of water and an organic liquid, or (2) mixing PFA, PPS, and a heat-resistant filler, compression-molding, and pulverizing.
