摘要： 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.

摘要： A composition containing less than 95 mol % of a trihydrofluorinated saturated hydrocarbon represented by the following formula (I) Rf1—R1—Rf2  (I) (wherein R1 represents a carbon chain in which CHF and CH2 are bound, and Rf1 and Rf2 are bound to each other to form a ring by a perfluoroalkylene chain of 2 to 4 carbon atoms) and the balance of a tetrahydrofluorinated saturated hydrocarbon having the same carbon number and the same carbon structure as the trihydrofluorinated saturated hydrocarbon, as represented by the following formula (II) Rf1—R2—Rf2  (II) (wherein R2 represents a carbon chain in which CH2 and CH3 are bound, and Rf1 and Rf2 are as defined above) is provided as a composition containing, in a high proportion, trihydrofluorocarbon, a hydrofluorocarbon (HFC) known to have a small global heating coefficient, which has less influence on the global environment, shows less toxicity to animals, and is chemically stable.
