摘要：A composition comprising at least one fluoropolymer and at least one solvent,wherein the solvent comprises a branched, partially fluorinated ether and wherein thepartially fluorinated ether corresponds to the formula:          Rf-O-R whereinRf is a perfluorinated or partially fluorinated alkyl group that may be interrupted once ormore than once by an ether oxygen and R is a partially fluorinated or a non-fluorinatedalkyl group; and wherein the fluoropolymer is a copolymer comprising at least 90 % byweight (based on the total weight of the polymer, which is 100 % by weight) of unitsderived from tetrafluoroethene (TFE) and one or more perfluorinated alkyl ethersselected from ethers corresponding to the general formula          R-O-(CF)-CF=CF wherein n is 1 in which case the ether is an allyl ether, or 0 in which case the ether isa vinyl ether and R represents a perfluoroalkyl residue which may be interrupted once ormore than once by an oxygen atom. Also provided are methods of preparing thecompositions and methods for coating substrate with the compositions.
