摘要： A subject-matter of the invention is a copolymer comprising at least 3 units, P1, P2 and P3, with the following general formulae: with X1, X2 and X3, which are identical or different, taken from the group of atoms consisting of H, F, Cl and Br; with R1 taken from the group of atoms consisting of H, F, Cl and Br; with R2 a carbonaceous group comprising from 1 to 10 partially or completely fluorinated carbon atoms; with Y1 and Y2, which are identical or different, taken either from the group of atoms consisting of H, F, Cl and Br or from the family of the carbonaceous groups comprising from 1 to 10 carbon atoms; with Y3 a carbonyl group or a divalent carbonaceous group; the content of P2 unit in the copolymer being between 30 and 70 mol % for respectively a content of P1 and P3 units in the copolymer of between 70 and 30 mol % and the weight-average molar mass (Mw) of the said copolymer being between 103 and 106 g/mol. Preferably, the copolymer is of CTFE/VCA/HFP or TFE/VCA/HFP type.
