The pyrolysis behaviour of a novel polyether-ketone with cardo has been studied by furnace type pyrolysis gas chromatography. The main pyrolysis fragments consist of CO, CO2 light hydrocarbons, bezene, phenol, diphenyl ether and chlorobenzene. When dichlorodiphenylketone is used in a surplus amount in the synthesis, the larger mole ratio of dichlorodiphenylketone to phenolphthalein is, the higher the chlorobenzene an end group fragment, content in the pyrolysis product will be.

由亲核缩聚反应合成了酚酞(PPh)-二氯二苯酮(DCBP)-对苯二酚(HQ)三元共聚物并对结构和性能作了初步鉴定。随PPh/HQ组成的不同可得到结晶或无定形聚芳醚酮。聚合物的玻璃化转变温度在143~228℃之间,且随pph含量而异。三元共聚物较酚酞聚芳醚酮(PEK-C)均聚物有更好的耐溶剂性及热稳定性。

Epoxy-terminated phenolphthalein polyaryletherketones (E-PEK) of M_n=1000~8000 were synthesized by reaction of epichhlorohydrin with PEK oligomer having—OK terminal groups prepared by condensation of phenolphthalein (PPH) with 4,4'-dichlorobenzophenone (DCBP) at molar ratios of PPH to DCBP from 1:0. 5 to 1:0. 9. The E-PEKs were characterized by IR and ~1H NMR spectra,initial glass transtion temperature (T_(gi)); the melting viscosity and solubility of E-PEK samples were also measured.

Epoxy-terminated phenolphthalein polyaryletherketones (E-PEK) of M_n=1000~8000 were synthesized by reaction of epichhlorohydrin with PEK oligomer having—OK terminal groups prepared by condensation of phenolphthalein (PPH) with 4,4'-dichlorobenzophenone (DCBP) at molar ratios of PPH to DCBP from 1:0. 5 to 1:0. 9. The E-PEKs were characterized by IR and ~1H NMR spectra,initial glass transtion temperature (T_(gi)); the melting viscosity and solubility of E-PEK samples were also measured. The E-PEKs were cured with 4, 4'-diaminodiphenylether (DDE) and the glass transition temperatures of the fully erosslinked E-PEK/DDE (T_(g∞)) were found to be in relation with the initial molecular weight of the oligomer. The T_(g∞) values for all samples closslinked were in the range of 183~215℃.
