摘　　要：以双酚A为起始剂,环氧丙烷(PO)为聚合单体,双金属氰化络合物(DMC)为催化剂,合成了一种相对分子质量为1 000的高性能聚醚多元醇。讨论了反应温度、催化剂浓度、PO预滴量等工艺条件对聚合反应的影响,并探索了该聚醚多元醇应用于聚氨酯弹性体对其力学性能的影响。结果表明,合成的双酚A基高性能聚醚多元醇具有较窄的分子量分布和低不饱和度值,应用于聚氨酯弹性体可显著提高材料的力学性能。A high performance polyether polyol with relative molecular weight of 1 000 was synthesized with bisphenol A as starting agent, propylene oxide(PO) as monomer and a double metal cyanide complex(DMC) as catalyst. The effects of reaction temperature, catalyst concentration and pre-droped PO dosage on the PO polymerization were discussed. Furthermore, the influence of the polyether polyol on the mechanical properties of the polyurethane elastomer was simply studied. The results showed that high performance polyether polyol had a narrow molecular weight distribution and low unsaturation value, which could improve the mechanical properties of polyurethane elastomer.
