New amorphous poly(arylene ether ketone)s with amide substituents were prepared via nucleophilic nitro displacement reaction. The dinitro monomer, 1,4‐bis[4‐nitro‐3‐(1‐piperidylcarbonyl)benzoyl]benzene, was synthesized through a masked acyl anion equivalent, bis(aminoacetonitrile). The weight average molecular weight ( M w ) of the polymers is about 40 000, the glass transition temperature around 200°C. The polymers are soluble in common organic solvents such as chloroform, 1,1,2‐trichloroethane, and N ‐methyl‐2‐pyrrolidone (NMP). The polymer from the dinitro monomer and bisphenol A is easily cast into a transparent and flexible freestanding film. 5% weight loss temperatures of the polymers are in the range from 409–418°C under N 2 .
