Abstract: | In order to develop a novel process for poly(arylene ether ketone)s with high thermal and chemical stability, a series of
poly(aylene ether ketone)s containing triazloe moieties were synthesized via the click chemistry of 4,4′-bis(azidomethyl)
diphenyl ketone (BADPK) and bisethynyl compounds (BEAE1-5). The resulting polymers were characterized by using IR and 1H NMR techniques. The solubility data showed that samples possessed good solubility in highly polar solvents. Molecular mass
of these samples was determined by GPC which indicated they exhibited reasonable molecules weights and relatively small polydispersity.
Furthermore, thermal stability of the samples was evaluated using thermogravimetric analysis (TGA) and differential scanning
calorimetry (DSC), which indicated that they possessed good thermal stability and high T
g (100–140 °C). All the polymers were amorphous confirmed by DSC and X-ray diffraction (WAXD). |
