EXAMPLE - 5 l Steel vertical autoclave equipped with a stirrer working at 650 rpm was utilized. After vacuum, 3500 cc of demineralized water and 35 ml of an aqueous microemulsion of perfluoropolyether were introduced in sequence into the autoclave. The reactor was heated up to 75 degrees C and 18 ml of 1,1,2,2-tetrafluoro-2-trifluorovinyloxy-ethanesulfonyl fluoride and 110 g of 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (initial load) were introduced. The pressure of 14 absolute bar was reached in the reactor by feeding tetrafluoroethylene. 35 cc Aqueous solution of initiator (ammonium persulfate) having a concentration of 20 g/l was introduced. During the polymerization, the reaction pressure was maintained constant at 14 bars by means of a continuous addition of tetrafluoroethylene. For each 10 g of tetrafluoroethylene introduced into the reactor, 3 ml of 1,1,2,2-tetrafluoro-2-trifluorovinyloxy-ethanesulfonyl fluoride and 16 g of 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole were charged. At the end of the polymerization a total of 413 g of 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole, 75 ml of 1,1,2,2-tetrafluoro-2-trifluorovinyloxy-ethanesulfonyl fluoride and 200 g of tetrafluoroethylene were introduced into the autoclave. The polymerization latex was coagulated with nitric acid to obtain amorphous fluorinated polymer.
