N－烯丙基苯甲酰亚胺单体合成及其复合材料的研究

Synthesis of DANT monomer and Polymer and Study on itsComposite

合成了新型的＂酰亚胶－双烯丙基＂类单体Ｎ－烯丙基（４－烯丙基甲酸酯）苯甲酸亚胺（ＤＡＮＴ）。优化的合成条件可使收率达９０％以上。确定了阶梯升温的固化程序，并用红外光谱法定性和定量地表征了预聚体固化程度的高低。研究了玻纤增强层压板的层压工艺条件，用裂解色谱－质谱联用技术分析了树脂浇铸体裂解机理，分析了其热定性，并对浇铸体、层压板的机械性能、电性能等进行了测试。ＤＡＮＴ树脂较ＤＡＰ、ＤＡＩＰ具有更优良的热氧稳定性、机械性能和电性能，显示了潜在的应用前景。

A kind of diallyl compounds containing 4-oxycarbonylphthaimimids unitwas prepared as allyl N-allyl-4-phthalimidocarboxylate.This compound waspolymerized by heating it in the presence of dicumylperoxide and/or benoylperoxide to afford network resin. The monomer and polymel was characterizedby IR, Elemental analysis, DTA techneques. The resin had essentially no weight loss upto 319℃ in air.Gas chromatography and mass-spectrometry simultaneous techniques was used to determine the mechanism of thermal decomposition. The laminate was fabricated by compression moulding at 170 - 180℃ in thepresence of the named initiators.
