Abstract: A type of novel crosslinkable poly(aryl ether ketone)s containing pendent phenylethynyl moieties(PEP-PAEK-Fn) were synthesized. The polymers were prepared by copolycondensation reaction of difluoro-monomer with potassium salt of 4-phenylethynylphenyl hydroquinone(PEP-PH) and 4,4'-isopropylidenediphenol(BPA). The Mns and Mw/Mns of polymers determined by GPC with polystyrene standard were 46700, 100000 and 1.6, respectively. The resulting polymers were thermally crosslinked at 370 ℃ for 2 h in N2 atmosphere. The glass transition temperature is increased after crosslinking. The cured polymers show a good chemical resistance and high thermal stability up to 500 ℃ under nitrogen.

Key words: Poly(aryl ether ketone), Diphenyl ethynel, Crosslinking
