<P>PROBLEM TO BE SOLVED: To provide tetrafluoroethylene resin-containing powder capable of stabilizing a slurry, and excellent in free flowability and a sieve passing property, in a method of producing the tetrafluoroethylene resin-containing powder. <P>SOLUTION: A coagulant is added into an aqueous dispersion containing a tetrafluoroethylene resin (A) and other thermoplastic resin (B), the tetrafluoroethylene resin (A) and the other thermoplastic resin (B) are coagulated to form the slurry, a solid matter is recovered thereafter from the slurry, and the solid matter is dried further, in the method of producing the tetrafluoroethylene resin-containing powder. The method of producing the tetrafluoroethylene resin-containing powder is constituted to recover the solid matter by holding the slurry at 60°C or more to a temperature higher by 25°C than a glass transition temperature of the thermoplastic resin (B) or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
