【摘要】 利用自制的双酚A衍生物Ph-BPA、三羟甲基丙烷为原料,通过A2+B3缩聚反应的方法,合成超支化双酚A衍生物环氧树脂(HPHEP),再对其末端基团进行改性,成功合成出超支化双酚A衍生物环氧丙烯酸酯(HPHEA)。通过红外光谱、紫外可见光谱以及核磁共振氢谱对其结构进行表征。HPHEA的热失质量曲线表明,其主要失质量温度区间为320~450℃,具有良好的耐热性。UV固化后,HPHEA涂膜展现出优良的力学性能。更多还原

【Abstract】 A hyperbranched bisphenol A derivatives epoxy resin( HPHEP) has been prepared by using the self-prepared bisphenol A derivative( Ph-BPA) and trimethylolpropane as raw materials via A2+B3 polycondensation. Further,a hyperbranched bisphenol A derivatives epoxy acrylate( HPHEA) is successfully synthesized by modifying the end group of HPHEP. The structure of polymers were characterized by FT-IR,UV-Vis spectra and1 H NMR spectra. The result of thermal gravimetric curve of the HPHEA shows that the main temperature range of weight loss is between 320 ~ 450 ℃,indicating a good heat resistance. In addition,the mechanical properties of the HPHEA UV-cured film exhibits excellent mechanical properties.更多还原
