摘要： Perfluoroalkylene oxide copolymer having acid fluoride moieties are prepared by reaction of hexafluoropropylene oxide and 1,2-epoxypentafluoropropane 3-fluorosulfate in the presence of a cesium alkoxide initiator. The copolymers may be cured at room temperature and are useful in sealant and coating formulations. Derivatives of the copolymers containing ester, amide, nitrile, and ether moieties are also disclosed.
