以蔗糖与甘油和环氧丙烷为起始剂合成蔗糖型聚醚多元醇，再将木薯淀粉与蔗糖型聚醚多元醇得到预聚体后，与二异氰酸酯发生聚合反应得到氨酯泡沫塑料。分别采用 GPC、IR、HNMR、SEM、DSC、TG、XRD 等测试手段分析产品的结构和性能，结果表明蔗糖型聚醚具有较高的羟值、较好的分子量分布和较高的反应活性。淀粉改性聚氨酯泡沫为共聚物，是一种无定型非晶态结构，淀粉的配比含量对泡沫结构性能有着直接影响。
以蔗糖與甘油和環氧丙烷為起始劑閤成蔗糖型聚醚多元醇，再將木藷澱粉與蔗糖型聚醚多元醇得到預聚體後，與二異氰痠酯髮生聚閤反應得到氨酯泡沫塑料。分彆採用 GPC、IR、HNMR、SEM、DSC、TG、XRD 等測試手段分析產品的結構和性能，結果錶明蔗糖型聚醚具有較高的羥值、較好的分子量分佈和較高的反應活性。澱粉改性聚氨酯泡沫為共聚物，是一種無定型非晶態結構，澱粉的配比含量對泡沫結構性能有著直接影響。

A sucrose-containing polyether polyol was synthesized from sucrose,glycerol and oxypropane. It used to react with Cassava Starch, then that it added diisocyanates to synthesize polyurethane foams. The method of GPC, IR, HNMR, SEM, DSC, TG, XRD were used to analyze the structure and properties of sucrose-containing polyether polyol and the starch modified polyurethane foams. The result showed that sucrose-containing polyether polyol had high hydroxyl value, evenly molecular weight distribution and high reactivity, and that the starch modified polyurethane foams were amorphous copolymers which structure and properties was influenced by added amount of cassava starch.
