摘　　要：本文合成了羟端、氟端和苯端三种不同端基的聚醚醚酮.结果表明,无活性的苯端聚醚醚酮具有最好的热稳定性.Two series of poly (etherether ketone) with two kinds of terminal groups were synthesized by polycondensation of 4, 4'-difluorobenzophenone, hydroquinone and 4-fluorobenzophenone in the presence of alkali metal carbonate and biphenylsulphone. For the PEEK with fluoro-terminal group, the relationship between the molar proportions of 4, 4'-difluorobenzophenone and hydroquinone and inherent viscosity was studied. For the PEEK with phenyl-terminal group, the relationship between per cent of 4-fluorobenzophenone and inherent viscosity was studied. The thermal stability of three kinds of PEEK having different terminal groups was investigated by Ml and UV.
