| 摘 要： | 以4-(4-羟基苯基)-2,3-二氮杂萘-1-酮(DHPZ)为原料,制得含二氮杂萘酮结构的聚芳醚砜预聚物(PPES),再与顺丁烯二酸酐反应得到不同聚合度的含二氮杂萘联苯结构的双马来酰亚胺(PPES-BMI)。采用FT-IR和1H-NMR对其分子链结构进行了表征,测试了聚合物分子质量和溶解性能。通过TGA分析和冲击性能测试研究了不同含量、不同聚合度的PPES-BMI对PPES-BMI/DGEBA复合体系热-力学性能的影响。结果表明,PPES-BMI含量增加,体系初始热分解温度和最大热失重温度上升;PPES-BMI质量分数为35%,DP=20的PPES-BMI/DGEBA共混体系的冲击强度最大,达到2.67 kJ/m2,增幅为75.8%。

| Abstract: | Novel bismaleimides containing phthalazine biphenyl(PPES-BMI) with different polymerization degrees were synthesized by the reaction of maleic anhydride with poly(aryl ether sulfone) prepolymer(PPES)containing phthalazinone prepared from 4-(4-hydroxyphenyl)-2,3-phthalazine-1-one(DHPZ).The structure of PPES-BMI was characterized by FT-IR and 1H-NMR spectra.The molecular weight and solubility of PPES-BMI were tested.The effect of differernt contents and polymerization degree of PPES-BMI on the thermo-mechanic... |
