Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: production of polyhexafluoropropylene oxides with reactive fluroanhydride groups through treatment with elementary fluorine while heating. The process is carried out in a single step in a nickel vertical vessel, filled with a spring washer. Elementary fluorine is directly fed into the reaction mass while heating to 120 to 240C. ^ EFFECT: design of an efficient method of producing chemical-resistant polyhexafluoroproylene oxides. ^ 2 ex Описан способ получения стабилизированных химически стойких полигексафторпропиленоксидов путем обработки полигексафторпропиленоксидов с реакционно-способными фторангидридными группами элементарным фтором при нагревании, причем процесс проводят в одну стадию в никелевом аппарате колонного типа, заполненного никелевой насадкой Гровера, путем подачи элементарного фтора непосредственно в реакционную массу при нагревании до 120-240°С.
