摘要:
The present invention aims to provide a novel method for producing an aqueous dispersion containing non-melt-processable polytetrafluoroethylene particles. The present invention relates to a method for producing an aqueous dispersion containing non-melt-processable polytetrafluoroethylene particles, the method including polymerizing tetrafluoroethylene in an aqueous medium in the presence of perfluoro hexanoic acid or its salt.
