ABSTRACT:
Perfluoropolyethers containing an approximate equal number of difluoromethylene and tetrafluoroethylene repeat units distributed either randomly or in alternating sequence along the polymer chain are disclosed. The polymers range in molecular weight from 500-200,000 amu; the lower molecular polymers being fluid and the intermediate and high molecular weight polymers being solid. The perfluorinated copolymers are synthesized by direct fluorination of corresponding methylene oxide/ethylene oxide copolymers.
