Claim:
A process for preparing a functional fluoro-copolymer, the process comprising combining one or more fluoromonomers and one or more functional fluoromonomer with an organoborane functional initiator and oxygen to copolymerize the monomers into a functional fluoro-copolymer having the following formula: wherein G—R is the residue of organoborane initiator, in which G is a functional group and R is a C 2–C 15 alkyl group or an aryl group, X and Y are independently hydrogen or halogen; p is from 1 to about 6; m is between 0 to about 40 mole %; n is between about 100 mole % to about 60 mole %, and J is a functional group, provided that at least one X or Y is a fluorine.
