中文摘要: 以端羟基聚醚和双乙烯酮为原料合成了新型端乙酰乙酸酯基聚醚,通过FT-IR、1H-NMR、13C-NMR等方法对其结构进行了表征。结果表明:聚醚与双乙烯酮反应生成端乙酰乙酸酯基聚醚的同时生成了可以稳定存在的烯醇结构的互变异构体。所合成的新型端乙酰乙酸酯基聚醚与胺端基化合物反应生成具有优良力学性能的聚醚亚胺材料。
Abstract:Novel acetoacetic ester-terminated polyether was synthesized by the reaction between polyether and diketene. The products were characterized by FT-IR、1H-NMR and 13C-NMR. Results show that acetoacetic ester-terminated polyether has an enol form tautomer and the tautomer is stable. This new kind of acetoacetic ester-terminated polyether can be used for the synthesis of polyether- imine elastomer which has good mechanical property.
