A polyfluorotriarylmethane polymer was prepared by the reaction of 3,5-diflurophenol (3,5-DFPh) with pentaflurobenzaldehyde (PFBA). The polymer obtained was characterized by NMR, FT-IR, UVVis, MS and Gel permeation Chromatography (GPC). It was found that phenolic ring in the polymer was connected at meta-position by methine carbon, and that molecular weight distribution of the polymer consists of mainly four components ranging from 6,000 to ca. 1,000,000. Further oxidation of this polymer generates the radicals which are stable in air for at least 3 months.
