Abstract: Fluorinterminated hyperbranched poly(ether ether ketone)(HPDEEK-F) was synthesized via A₂+B₃ reaction. HPDEEKF was endcapped with 4-phenyl ethynyl phenol, which received phenylethynylterminated hyperbranched poly(ether ether ketone)(HPDEEK-PEP). The structures and performances of poly(ether ether ketone)s were confirmed by FTIR, ¹H NMR, DSC and TGA. The experimental results show that the T_g and the thermal stability of HPDEEKPEP are higher than those of HPDEEKF. They all have a good solution property.

Key words: hyperbranched poly(ether ether ketone), fluorinterminated, phenylethynylterminated
