Fluoropolymers are disclosed. The fluoropolymers include (i) units derived from a fluoromonomer having the formula F2C=CXY, where X is CF3 and Y is either F or CF3, and (ii) units derived from at least one donor monomer. In the disclosed fluoropolymers, units (i) and (ii) are distributed along the fluoropolymer chain in a substantially alternating fashion. Also disclosed are thermosetting compositions containing such fluoropolymers, substrates coated with such compositions, methods for making such compositions, and methods for coating substrates with such compositions.
L'invention concerne des fluoropolymères. Les fluoropolymères selon l'invention comprennent (i) des unités dérivées d'un fluoromonomère représenté par la formule F2C=CXY, dans laquelle X représente CF3 et Y représente soit F soit CF3, et (ii) des unités dérivées d'au moins un monomère donneur. Dans les fluoropolymères selon l'invention, les unités (i) et (ii) sont réparties sensiblement en alternance le long de la chaîne fluoropolymère. L'invention a également trait à des compositions thermodurcissables contenant de tels fluoropolymères, à des substrats revêtus desdites compositions, à des procédés de production desdites compositions, et à des procédés de revêtement de substrats à l'aide desdites compositions.
