Abstract:
New high molecular weight fluoropolymers (fluoropolymer surfactants) are provided that are useful in compositions for use as fire extinguishing concentrates. The fluoropolymers contain C4-C6 perfluoroalkyl groups, and substantially lack perfluoroalkyl groups containing more than 6 fluorine-substituted carbon atoms.
