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.
提供一种在碱或水和热中具有优异清洁作用、不燃性和高稳定性的含氟碳氢化合物;以及一种含聚合物的溶液,其制备方法是将一种具有成膜能力的聚合物(最好是含氟聚合物)溶解或分散在一种含三氢氟碳的溶剂中。更具体地说,本发明提供了由下式表示的含 4 至 6 个碳原子的含氟碳氢化合物,其碳原子数在 95% 或以上,以及含有该碳氢化合物的聚合物溶液:
Rf1-R1-Rf2 (I)
其中 R1 代表相互结合的 CHF 和 CH2 碳链;Rf1 和 Rf2 独立地代表全氟烷基;Rf1 和 Rf2 可以相互结合,形成一个环。
