Perfluoroglycidyl ethers of the formula
are prepared by epoxidation of a polyfluorodiallyl ether of the formula
The glycidyl ethers are useful as monomers for preparing polymers which provide crosslinking or cure sites and are stable elastomeric materials useful as sealants, caulks, and fabricated objects.
Allyl-, propargyl- and allenyl- tin curatives for fluoroelastomers with nitrile cure sites provide rapid curing combined with excellent stability in aqueous environments.
