| Abstract: | 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-resistance and excellent chemical-resistance. |
| Keywords: | Low temperature solution polycondensation Friedel-Crafts acylation Polyaromatic ether ketone ketone Diphenyl ether |
