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.

摘要： A fluorinated oligomer having COOH groups at both end and a &rgr;50° value of 1,000 to 10,000 is produced by swelling a fluorine rubber crosslinking product in an organic solvent, followed by decomposition in the presence of a base and a peroxide. The obtained fluorinated oligomer is soluble in solvent and thus easy to separate from fillers, etc., and can be effectively used as a chain-elongating agent for epoxy resin, isocyanate resin, oxazoline resin, etc.
