Novel compounds of the formula ARE PROVIDED WHEREIN X is -COF, -COCl, -COOH, -COOR, -COOM, -CONR1R2, or -CN wherein R is an alkyl radical, M is a metal, and R1 and R2 are independently hydrogen or alkyl radicals. Also provided are novel compounds of the formula C6F5OCF2CF2CF2OCF(CF3)- X wherein X is as defined above. These novel compounds are useful in the preparation of perfluoro(3-phenoxypropyl vinyl ether) monomer, said monomer being useful in the preparation of copolymers having improved oxidative stability.
