Title:
FLUORINATED HYDROCARBONS, DETERGENTS, DETERGING METHOD, POLYMER-CONTAINING FLUIDS, AND METHOD OF FORMING POLYMER FILMS
Document Type and Number:
WIPO Patent Application WO/1998/051651
Kind Code:
A1
Abstract:
Incombustible fluorinated hydrocarbons excellent in detergency and stabilities to alkalis, water and heat; and polymer-containing fluids obtained by dissolving or dispersing a film-forming polymer, preferably a fluoropolymer in a solvent containing a trihydrofluorocarbon. Specifically, fluorinated hydrocarbons containing at least 95 % of trihydrofluorocarbons represented by the following general formula and having 4 to 6 carbons; and polymer-containing fluids each containing the fluorinated hydrocarbon: Rf�1?-R�1?-Rf�2? wherein R�1? is a carbon chain composed of CHF and CH�2?; and Rf�1? and Rf�2? are each perfluoroalkyl, or Rf�1? and Rf�2? are bonded together to form a ring.
