A fast and highly efficient approach to hyperbranched poly (aryl ether ketone)s (HPAEKs) via the polycondensation of A2 and BB’2 monomers has been described. Commercially available hydroquinone (A2 monomer, HQ) and effortlessly synthesized 2,4’,6-trifluoro-benzophenone (BB’2 monomer, TF) were thermally polycondensed to prepared fluoro or phenolic-terminated hyperbranched poly(aryl ether ketone)s with K2CO3 and Na2CO3 as the catalysts. Analyses of FTIR and 1H-NMR spectra revealed the structures of the resultant polymers. These hyperbranched polymers exhibit excellent solubility in generally organic solvents and possess moderate molecular weights with broad distributions determined by gel permeation chromatograms (GPC).
Keywords:hyperbranched;synthesis;BB’2 monomer
