摘要：
Polyfluoro .gamma.-ketoester compounds are obtained by reaction of ethylenic monoolefins, a metal or quaternary ammonium cyanide, and a fluoroester. These compounds, which have a general formula R.sub.F C(O)CFYCF.sub.2 CO.sub.2 R.sup.1, can be copolymerized directly with fluorinated ethylenic monoolefins, or further reacted to form vinyl ether and allyl ether derivatives which may also be copolymerized with ethylenic comonomers, forming solid, moldable copolymers with useful properties determined by the nature of pendant functional groups R.sub.F.
