摘要：

Nonequilibrium plasma polymerization of hydrofluorocarbon HFC-134a (CF3CH2F) in argon bath gas has been studied in a dielectric barrier discharge reactor at atmospheric pressure and in the absence of oxygen and nitrogen. The reaction resulted in the formation of a polymeric solid fraction and the noncrosslinked properties of this material assisted in its characterization by solution state C-13 and F-19 nuclear magnetic resonance spectroscopy. Gel permeation chromatography revealed that the polymers include low (number average molecular weight, Mn values between 900 and 3000 g mol(-1)) and high (Mn approximately 60 000 g mol(-1)) molecular weight fractions. A detailed polymerization mechanism is proposed, based on the published literature and the findings of the current investigation.
