Abstract: The present invention provides hardenable fluoridated copolymers that are prepared by (a) copolymerizing tetrafluoroethylene, vinylidene fluoride, and an allylic monomer of the formula ##STR1## wherein R is an unsaturated linear, branched, or cyclic alkyl chain having 2 to 12 carbon atoms, each of R1, R2, R3, and R4 is independently selected from the group consisting of H, CH.sub.3, CH.sub.2 CH.sub.3, OH, and CH.sub.2 OH, n is 0 or 1, and p is a value from 0 to 3, in the presence of a copolymerization initiator and in a solvent medium, and subsequently (b) extracting the copolymer from the reaction medium by precipitation in a liquid that is not a solvent of the copolymer but is miscible with the solvent of the reaction medium. The fluoridated copolymers so prepared are useful in powder form for electrostatic spray coating applications.

Abstract: A settable copolymer containing the copolymerization remnants of a fluoridated monomer and an allylic derivative characterized in that:a) The remnants of the fluoridated monomer are derived from the association of tetrafluoroethylene and vinylidene fluoride.b) The allylic derivative has the formula: ##STR1## with R representing a linear, branched, or cyclic alkyl chain, not saturated, and having 2 to 12 carbon atoms.R1, R2, R3, and R4, may be identical or different, being chosen from among: H, CH.sub.3, CH.sub.2 --CH.sub.3, OH, CH.sub.2 OHn is 0 or 1p is a value from 0 to 3.This settable copolymer is obtained by copolymerization in solution in an organic solvent. This copolymer is used in powdered paints.
