Abstract: Compounds R - ( - M - O -)p - (- M - O - O)q-R1 where M is a unit derived by the opening of double bond of one or more perfluoroolefins; R and R1 are - COR", -CF2-COR", -CF(CF3)COR", -O - CF2 - COR", -O-CF(CF3)-COR" -O-O-CF2-COR" and -O-O-CF(CF3)-COR" (where R" is formed from F, OH or OR"' 1/m or NH2 with an alkoxy radical; R"' is a metal of valency m); p and q are at most 100; one or other may be O; (p + q) is 1-100; the (-M-O) and -(M-O-O) units are arranged at random along the polymer chain). M is pref. formed from a perfluoroethylene, perfluoropropylene and tetrafluoroethylene.
