Hyperbranched poly(aryl ether ketone)s were prepared by polymerization of hydroquinone (A2) and 1,3,5-tris[4-(4-fluorobenzoyl)phenoxy]benzene (B3). The gelation of hyperbranched poly(aryl ether ketone)s was effectively avoided. Hydroxyl-terminated (HPAEK-OH) and fluoro-terminated (HPAEK-F) hyperbranched poly(aryl ether ketone)s were prepared by using different A2/B3 mass ratio. The structure of the B3 monomer was confirmed by MS, 1H NMR/IR. The glass transition temperatures of the HPAEK-F and HPAEK-OH are 114°C and 162°C respectively. Thermal stability of HPAEK-F is higher than HPAEK-OH.
