摘要

•Granulated commercial grade polystyrene was re-precipitated to powder with particle size about 0.5 mm.•Polymer powder was fluorinated with fluorine in a liquid perfluorinated medium.•It was shown that hydrogen-substituting fluorination in main chain and benzene ring prevails in the fluorination process.
