실험 절차

A 400 ml autoclave was loaded with 200 ml water, 1.09 g of C8F17SO2Li, and purged with nitrogen. The autoclave was cooled, evacuated, and loaded with 60 g of hexafluoropropylene and 40 g of vinylidene fluoride. A solution of 0.5 g of sodium bromate in 50 ml of water was injected at 0.3 ml/minute. Pressure within the autoclave decreased from 2.15 MPa at 22° C. to 1.65 MPa at 24° C., 3 hours later. The autoclave was vented, the polymeric emulsion recovered and then broken by freezing. Filtering and drying gave 38 g of hexafluoropropylene/vinylidene fluoride copolymer with an inherent viscosity of 0.37.
