Reactivity Ratio of Emulsion Copolymerization of Fluorinated Gaseous Monomers-Vinylidene Fluoride and Hexafluoropropylene

摘要：

The apparent reactivity ratios of hexafluoropropylene (HFP)/vinylidene fluoride (VDF) emulsion copolymerization were studied by nonlinear fitting according to the copolymer composing equation, which, according to the calculation, are 1.88 and 0.86 respectively. The constitution of mixed gaseous monomers was measured through the gas chromatography. The copolymer compositions before and after reaction were measured by 19F-NMR. The calculated contents of VDF and HFP have nice accordance with the results from 19F-NMR analysis, which demonstrates that the method reported here is fairly reliable, and shed a light on the industryscale consideration for the emulsion copolymerization of HFP and VDF.
