Poly-hexafluoropropylene oxide(HFPO) with monofunctional acyl fluoride will be used as the reaction intermediate for high performance lubricant, anti-reflection and anti-fouling materials In this study, we report on the polymerization of HFPO initiated by monofunctional catalyst and the relation of the rate of HFPO addition and the ratio of HFPO-catalyst-solvent for the molecular weight build-up. Monofunctional catalsyt is synthesized by the combination of cesium fluoride, HFPO and tetraglyme. The molecular weight was characterized by 19F nuclear magnetic resonance (19F-NMR). The detailed experimental results concerning the factor for will be described. |
