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.”
Claims18
A fluorinated copolymer of formula (I) below:
- poly[Aa-co-(X-E-X)b] (I)
- in which A is a fluorinated monomer, X is a fluorinated monomer having a double bond which has an electron acceptor nature;
- X is capable of copolymerizing with, said monomer A and, and also with a monomer E in an alternating manner, E being a monomer bearing a functional or functionalizable group having a double bond which has an electron donor nature;
- a and b are the molar ratios of the monomer A and of the triad X-E-X, respectively, a being greater than 0.85, and b being less than 0.15, and greater than 0;
- the X:E molar ratio is greater than or equal to 2.
