Abstract: A composition is provided that is capable of abating combustion of a Li-ion battery, comprising liquid fluoropolyether and at least one combustion abatement agent being other than fluoropolymer, examples of such agent including one or more compounds that exhibit one or more of the following characteristics of being a hydrate, carbonate, bicarbonate or sulfate, or are phosphorus or bromine containing or that form a char and/or exhibit intumescence upon heating.

Abstract: A process for making fluoropolymer resin comprising polymerizing at least one fluorinated monomer in an aqueous medium containing initiator and polymerization agent comprising fluoroether carboxylic acid or salt thereof to form an aqueous dispersion of particles of fluoropolymer. The fluoroether carboxylic acid or salt thereof employed in the process has the formula: [R1—O-L-COO?]Y+ wherein R1 is a linear, branched or cyclic partially or fully fluorinated aliphatic group which may contain ether linkages; L is a branched partially or fully fluorinated alkylene group which may contain ether linkages; and Y+ is hydrogen, ammonium or alkali metal cation. Wet fluoropolymer resin is isolated from the aqueous medium. The wet fluoropolymer resin is to produce a dry fluoropolymer resin and to decarboxylate the residual fluoroether carboxylic acid or salt to produce a vapor of fluoroether byproduct. The vapor of fluoroether byproduct is captured.
