Description: The reaction of HFC-134a (CF3CH2F) in an argon bath gas has been studied using a dielectric barrier discharge non-thermal plasma at atmospheric pressure. Oxygen and nitrogen have been excluded in the reaction. It has been found that CF3CH2F can be converted into a non-crosslinked polymer under the reaction conditions studied. Other products include CHF3, CH2F2, C2H3F, C3H3F5, H2, HF and an oligomeric product fraction. The discharge characteristics of argon diluted CF3CH2F has been discussed, which is in the transition region between filamentary and homogeneous glow. The conversion of CF3CH2F ranges from 52% to 82 % for the applied voltage range of 13.4 – 15 kV (peak-peak) and input energy density range of 2 - 12 kJ/L. A simplified reaction mechanism has been proposed. Gel permeation chromatography analysis show two fractions with top molecular weights (Mp) of 2400 and 105,000 g/mol respectively, produced at an input energy density of 8 kJ/l.
