In this study is reported the synthetic procedure and the characterisation of novel phosphorus containing polyether ether ketone (PEEK‐P). The new polymer was synthesized via direct polycondensation of 2,2‐bis(3‐diethylphosphono‐4‐hydroxyphenyl)‐propane and 4,4′‐difluorobenzophenone according to well known general procedure and was extensively characterized by using infrared spectroscopy (FT‐IR), thermogravimetric analyses (TGA), viscosity measurements and † H‐NMR analysis. The obtained polymer is soluble in some organic solvents and the solution of phosphonated polymer could be used to obtain membranes by using the phase inversion technique.
