用 DSC、TGA、TBA 和元素分析等方法研究糠醇(FA)缩聚和 FA 与 THEIC〔三(2—羟乙基)异腈酸尿酯〕共缩聚交联反应。发现 FA 缩聚和 FA 与 THEIC 共缩聚的反应均有四个放热反应峰(见图1)。Ⅰ和Ⅱ峰(50～80℃)为 FA 头—尾、头—头醚化线
The copolycondensation of furfuryl alcohol (FA) with FA and THEIC [poly (2-hydroxyethyl) isocyanurate) co-condensation reaction was studied by DSC, TGA, TBA and elemental analysis. It was found that there were four exothermic reaction peaks for FA polycondensation and FA and THEIC copolycondensation (see Figure 1). Peaks Ⅰ and Ⅱ (50 ~ 80 ℃) are FA head-tail and head-head etherification line
