The results showed that the preoxidation of PPESK was a free radicals reaction,which was initiated by the decomposition of proton in aromatic ring and sulfone functional group and the removal of H_2O and SO_2.When the preoxidation temperature was above 460℃,the radical reaction was initiated by the decomposition of ketone functional group and the removal of CO_2.At last,the three-demensional cross-linking structure containing polyaromatic ether and biphenyl was formed.
研究表明,PPESK的预氧化过程是一个自由基反应过程,始终伴随着芳香环质子和砜基官能团的脱除引发的自由基交联反应,脱出H_2O与SO_2;当预氧化温度超过460℃后,随着反应的进行,由羰基官能团分解引发的自由基交联反应开始发生,脱出CO_2,并最终形成了含有大量聚芳醚和联苯结构的稳定的三维空间网状结构,进而完成PPESK由热塑性材料向热固性材料的转化。

By applying density functional theory, the relationships between the electron structures and the complexation of the two types of bis-β-diketone ligands (dithiol-γ-linked or alkyl-γ-linked) were investigated, based on the polarized continuum model of the self-consistent reaction field. Using the model B3LYP/6-31G**, the geometries of the ligands were optimized and the electron structure changes calculated.

The result showed that, the effect of the synergistic reaction of alkyl-phenol-polyoxythylene ether phosphate dispersant TERSPERSE 4896, nonyl phenyl polyoxyethylene ether dispersant TERSPERSE 2210 and XG to suspension was different. Both the rheological curves were same presented as pseudoplastic fluid when they stored in R. T (18~25℃) for 10 days, but the rheological curve of suspension with the synergistic reaction of TERSPERSE 2210 and XG was changed to dilatant fluid when it stored in R.
