Title:
FLUORINATED, SATURATED HYDROCARBONS, COMPOSITIONS THEREOF, POLYMER-CONTAINING FLUID, AND METHOD OF FORMING POLYMER FILM
Document Type and Number:
WIPO Patent Application WO/1998/051649
Kind Code:
A1
Abstract:
Compositions comprising linear or cyclic fluorinated, saturated hydrocarbons of the following general formula (I) Rf�1?-R�1?-Rf�2? and (II) Rf�1?-R�2?-Rf�2, and the use thereof. Each composition comprises more than 10 molar % and less than 95 molar % of a compound of general formula (I) and the balance of a compound of general formula (II). These compositions have an excellent chemical stability and a high safety for the living bodies, do not deplete the ozonosphere, and are usable for forming solvents for polymers, particularly for forming polymer films. In said formulae, R�1? is a carbon chain composed of CHF and CH�2?; Rf�1? and Rf�2? are each perfluoroalkyl, fluorine or hydrogen with the proviso that at least one of them is perfluoroalkyl, or Rf�1? and Rf�2? are bounded together to form a ring containing a perfluoroalkylene chain; and R�2? is a carbon chain composed of CHF and CHF, with the proviso that the skeletons of the compounds of formulae (I) and (II) are the same.
