Abstract: The present disclosure relates to a method of treating a substrate comprising an elastomeric material, wherein the method comprises the steps of: a) providing a composition comprising: i. at least one fluoropolymer which is a copolymer comprising at least 90% by weight, based on the total weight of the copolymer, of units derived from tetrafluoroethene (TFE) and from one or more perfluorinated alkyl ethers corresponding to the general formula (I): Rf1—O—(CF2)n—CF?CF2 (I) wherein n is 1 or 0 and Rf1 represents a perfluoroalkyl residue which is optionally interrupted once or more than once by an oxygen atom; and ii.

Abstract: 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.

Abstract: Described herein is method of functionalizing fluorinated polymers, wherein a reaction compound is grafted onto a fluorinated polymer, wherein the fluorinated polymer comprises at least one Br, I, and Cl group and is free of —CH2CH2— linkages. In one embodiment, the functionalized fluorinated polymer comprises a perfluorinated polymer backbone with pendent groups therefrom is disclosed, wherein at least one pendent group is according to formula I: where Rf is a bond, or a divalent perfluorinated group, optionally comprising at least one in-chain ether linkage; Z is I, Br, or Cl; and X comprises a functional group selected from the group consisting of an alcohol; phosphorous acid and salts thereof; phosphoric acid and salts thereof; a silane; an amine; an amide; a hydrocarbon, optionally comprising an in-chain oxygen, nitrogen, or sulfur linkage; a carboxylic acid and salts thereof; an ester; a sulfonyl fluoride, a sulfonic acid and salts thereof; and combinations thereof.
