Synthesis and Characterization of Hydrogen-bonded Polyaryletherketone Copolymers

A series of hydrogen-bonded polyaryletherketone copolymers was synthesized by the reaction of a mixture of phenolphthalein and 3,3'-bis (4-hydroxyphenyl)-isobenzopyrrolidone with equivalent mole of bis (4-nitrophenyl)ketone using anhydrous K_2CO_3 as catalyst and DMSO as solvent. The intermolecular hydrogen bond in the copolymers prepared was confirmed from FTIR spectra at different temperature. Compared with unmodified phenolphthalein based polyaryletherketone(PEK-C), the introduction of lactam ring groups onto PEK-C backbone led to a significantly higher glass transition temperature , better chemical solvent-resistant property and excellent mechanical tensile property.
