Poly(arylene ether ketones) with preset molecular weights (reduced viscosity from 0. 2 to 0.82 dL g−1) containing terminal phenolic groups were synthesized by the reactions of 4,4′-difluorobenzophenone with bisphenol A or phenolphthalein in the presence of K2CO3 in N,N-dimethylacetamide. The influence of an excess of bisphenols on the molecular weights of the polymers obtained was studied. The structures...
