ABSTRACT:
A process for making fluorovinyl ethers having the formula CFX═CXOCF2OR, wherein R is a C2-C6linear, branched or C5-C6cyclic (per)fluoroalkyl group, or a C2-C6linear, branched (per)fluoro oxyalkyl group containing from one to three oxygen atoms; when R is fluoroalkyl or fluorooxyalkyl group as above defined, it can contain from 1 to 2 atoms, equal or different, selected from the following: H, Cl, Br, I; X=F, H; and homopolymers or polymers obtainable by polymerizing said Fluorovinyl ethers with at least another polymerizable monomer.
