실험 절차

A 400 ml autoclave was loaded with 100 ml water and 1.0 g of C8F17SO2Li. The autoclave was cooled, evacuated, and loaded with 75 g of hexafluoropropylene and 50 g of tetrafluoroethylene. A solution of 0.5 g of sodium bromate in 50 ml of water was injected over about 3 to 4 hours at 20° to 25° C. The autoclave was vented, the polymeric emulsion recovered, and the emulsion broken by freezing. Filtering, washing 10 times with 200 ml of 1:1 methanol/water, and drying under vacuum gave 31 g of hexafluoropropylene/tetrafluoroethylene copolymer too high in molecular weight to extrude in a melt index apparatus at 372° C. with a 15 kg weight.
