Abstract
The invention relates to a fluorinated copolymers which are particularly based on vinylidene fluoride (VDF) or trifluoroethylene (TrFE) and particularly functionalized by functional and/or functionizable vinyl ethers. The invention also relates to methods for producing said copolymers, and to the applications thereof.
Claims19
A fluorinated copolymer of formula (I) below:
- poly[A-co-X-co-(X-E-X)] (I)
- in which A is a fluorinated monomer, X is chlorotrifluoroethylene (CTFE);
- X is capable of copolymerizing with, said monomer A and, also with a monomer E in an alternating manner, E is vinyl ether of formula CH2═CH—O—R in which R is selected from the group consisting of:
- alkyls;
- glycerol, saccharide;
- halogenated groups;
- thiols, silanes, sulfonic acid, phosphonic acids, azides, alkynes, carbonates, amines, ammoniums, amidine, aldehyde, isocyanate, urea, sulfonates, phosphonates, silicones, and fluorinated or hydrocarbon-based polymers and oligomers;
- wherein A is selected from the group consisting of vinylidene fluoride (VDF), trifluoroethylene (TrFE) or mixtures thereof and wherein the proportion of moieties derived from the monomer A is greater than 85 mole %.
