分别以四种生物质废弃物———木粉、榛子壳、稻草和玉米秆苯酚液化物为原料,与环氧氯丙烷反应,制备出以四种生物质液化物为基材的环氧树脂,采用凝胶渗透色谱（GPC）对比分析了四种生物质液化物及其环氧树脂的相对分子量分布。以聚酰胺（PA-650）为固化剂进行固化,并利用热失重分析（TGA）、差热分析（DSC）和剪切强度测试等手段对固化物的热力学性能进行了测试。结果表明,木粉液化物及其树脂的-Mw和-Mn最高分别为532、759和249、308,木粉基树脂胶粘剂的剪切强度最大为5.7MPa,且它的热稳定性最好。
Four kinds of feedstock（wood,hazelnut shell,rice straw and corn barn） were liquefied in phenol and the products were co-condensed with epichlorohydrin to obtain liquefied four kinds of feedstock-based epoxy resins respectively.The average molecular weight of liquefied products and their corresponding epoxy resins were examined by gel permeation in chromatography（GPC）.The epoxy resins were cured with polyamide-650（PA-650） and the thermal and mechanical properties were evaluated by thermogravimetric analysis（TGA）,differential scanning calorimetry（DSC） and lap shear strength measurement.The results show that they have a wide molecular weight distribution and exhibits high adhesion strength and thermal stability.Furthermore,the high molecular weight of rice straw products showed the best thermal stability.
