igh molecular weight polyaromatic ether ketone ketones (PEKK) were prepared by low emperature solution polycondensation of diphenyl ether (DPE) and terephthaloyl chloride (TPC)
isophthaloyl chloride (IPC) in presence of aluminum chloride
1
2-dichloroethane and N
N-dimethylformamide (DMF). The effects of some factors on polycondensation were investigated. The copolymers were characterized by IR
X-ray diffraction DSC
TG
etc. It is shown that melting temperatures
glass transition temperatures
crystalline temperatures of PEKK products decrease with increasing of mole ratios of IPC to TPC. The pekk prepared have good heat-resis-tance and excellent chemical-resistance.
