Abstract
Fluorinated ethers are provided that contain two functional end groups (ester and iodide groups) separated by a plurality of difluoromethylene, fluoro-trifluoromethylmethylene and oxygen groups. The compounds are useful as intermediates, particularly in the synthesis of fluoroalkylether difunctional compounds which can be used in the preparation of improved thermally stable polymers.
