摘要:
The present invention relates to a method for preparing hexafluoropropylene oxide with high yield, and particularly to a method for preparing hexafluoropropylene oxide comprising the step of performing a two-phase interfacial reaction between an organic phase containing hexafluoropropylene and an aqueous phase containing a hypochlorite oxidant in the presence of a phase-transfer catalyst and a non-ionic surfactant to improve the degree of emulsification and dispersion of the organic phase and to increase the contact interfacial area, thereby increasing the efficiency and the yield of the reaction.

摘要:
The present invention relates to a fluorine-containing graft copolymer and its manufacturing method. In particular, the fluorine-containing graft copolymer synthesized by copolymerization of copolymerizable perfluoroalkyl compound as a main chain and macromonomer having copolymerizable vinyl group at one end as branched chains, respectively. Thus the graft copolymer has the remarkable affinity to the substrates designed for the surface modification and superior performance than random copolymers, when it is employed as various types of surface modifiers of fluorine-containing compounds (e.g., water and oil repellent, soil release agents, mold-releasing agents, etc.).
