摘要： A process for producing filler-containing polytetrafluoroethylene granules according to an underwater agitation granulation method, in which there can be obtained filler-containing polytetrafluoroethylene granules being reduced in detachment of filler and excelling in fluidity and in which any discharge of polytetrafluoroethylene emulsion into waste liquid can be avoided. There is provided a process for producing filler-containing polytetrafluoroethylene granules characterized in that in the stage of granulation of a mixture of polytetrafluoroethylene powder and a filler by agitating in water in the presence of a liquid organic matter hardly soluble in water, a polytetrafluoroethylene emulsion and a coagulant are added to thereby effect coagulation of the polytetrafluoroethylene emulsion on a surface layer of filler-containing polytetrafluoroethylene granules.

摘要： To provide a powder primer composition excellent in adhesion properties and a laminate obtained by using it. The power primer composition comprises a powder made of a reactive ethylene/tetrafluoroethylene copolymer containing repeating units (A) based on tetrafluoroethylene, repeating units (B) based on ethylene, and repeating units (C) based on a monomer having an acid anhydride residue and a polymerizable unsaturated bond, wherein (C)/((A) + (B)) is from 1/10,000 to 5/100 by molar ratio; and a powder made of an epoxy resin having an epoxy equivalent of from 500 to 2,700 and a softening point of at least 70°C; wherein the mass ratio of the powder made of a reactive ethylene/tetrafluoroethylene copolymer to the powder made of an epoxy resin is from 99/1 to 80/20.
