Described herein is method of adding a non-fluorinated carbon-carbon double bond to a highly fluorinated polymer via an amidine linkage. In one embodiment, the derivatized fluorinated polymer comprising a highly fluorinated polymer backbone with pendent groups therefrom is disclosed, wherein at least one pendent group is according to the formula: (I) where Rf is a bond or a divalent perfluorinated group, optionally comprising at least one in-chain ether linkage, R is H, an alkyl group, or —CH(R″)X; R′ is H or an alkyl group; X is a monovalent group comprising at least one non-fluorinated carbon-carbon double bond; and R″ is H or an alkyl group. Such derivatized fluorinated polymers may be used in curable compositions and articles therefrom.
