The AB and AB2 monomers for flexible linear and hyperbranched polyetherketones were synthesized and they were in-situ polymerized in the presence of MWNT to afford corresponding nanocomposites. The reaction medium, PPA/P2O5 mixture as an electrophilic substitution reaction is indeed benign but strong enough to promote the covalent attachment of polyetherketones onto the surface of the electron-deficient MWNT.
