ABSTRACT OF THE DISCLOSURE Purified hexafluoropropylene oxide is produced by scrubbing to remove impurities that inhibit polymerization of hexafluoropropylene oxide, thus permitting the preparation of polymers having a degree of polymerization of more than 200, including end-capped and chain-extended derivatives thereof. The polymers are useful, depending on the molecular weight and various physical characteristics, as high performance elastomers, viscosity improvers for synthetic lubricants, or building blocks for preparing such viscosity improvers and high performance elastomers.
