Abstract

PURPOSE: To prepare a tetrafluoroethylene-hexafluoroethylene copolymer having such as excellent heat stability that the melt viscosity will not decrease even at a temperature over 400°C, by copolymerizing the monomers in suspension in the presence of a specific polymerization initiator and a molecular weight modifier.
