PREPARATION OF TETRAFLUOROETHYLENEHEXAFLUOROPROPYLENE COPOLYMERS

PURPOSE:To prepare tetrafluoroethylene-hexafluoropropylene copolymers with excellent thermal stability, without the shrinkage in secondary melting with heat after shaping, by the copolymerization in an aqueous medium in the presence of a specific polymerization initiator and a molecular weight modif...
