| abstract |
The present invention relates to a copolymer comprising fluorinated units of formula (I): (I) -C1X2-CX3X4- in which each of X1, X2, X3 and X4 is independently chosen from H, F and alkyl groups comprising from 1 to 3 carbon atoms which are optionally partially or totally fluorinated; units of formula (III): (III) -CXAXB-CXCZ- in which each of XA, XB and XC is independently chosen from H, F and alkyl groups comprising from 1 to 3 carbon atoms which are optionally partially or totally fluorinated, and Z is a polarisable group of formula-Y-Ar-R; Y being an O atom, or an S atom, or an NH group, Ar being an aryl group, preferably a phenyl group, and R being a monodentate or bidentate group comprising from 1 to 30 carbon atoms; and the copolymer having an enthalpy of fusion of greater than or equal to 5 J/g. The present invention also relates to a method for producing this copolymer, to a composition comprising this copolymer, and also to an ink and a film obtained from said copolymer. |
