Fluorinated hydrocarbons, detergents, deterging method, polymer-containing fluids, and method of forming polymer films

Abstract

Providing a fluorinated hydrocarbon with excellent cleaning action, incombustibility and high stability in alkali or water and heat; and a polymer-containing solution prepared by dissolving or dispersing a polymer with film-forming potency, preferably a fluoropolymer, in a solvent containing trihydrofluorocarbon. More specifically, a fluorinated hydrocarbon containing trihydrofluorocarbon with 4 to 6 carbon atoms at 95% or more, as represented by the following formula, is provided, together with a polymer-containing solution containing the same: Rf1—R1—Rf2   (I) wherein R1 represents a carbon chain of CHF and CH2, bound to each other; Rf1 and Rf2 independently represent a perfluoroalkyl group; and Rf1 and Rf2 may be bound to each other, to form a ring.

Dependencies are inferred from the claim text.
