FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing polytetrafluoroethylene particles. Disclosed is a method of producing polytetrafluoroethylene particles, comprising carrying out suspension polymerisation for tetrafluoroethylene in an aqueous medium to obtain suspension-polymerised polytetrafluoroethylene particles, washing, and then crushing the suspension-polymerised particles or crushing the suspension-polymerised particles with washing to obtain crushed particles, dehydration of crushed particles to obtain crushed particles characterized by a water content of 40 wt.% or less, and conducting heat treatment for dehydrated crushed particles to produce polytetrafluoroethylene particles; methods of producing a polytetrafluoroethylene moulded article and a polytetrafluoroethylene compression moulded article, including the disclosed method of producing polytetrafluoroethylene particles.
EFFECT: production of polytetrafluoroethylene particles characterized by a weakened sour smell.
