采用带有醚键的二异氰酸酯1，2-二（异氰酸酯）乙氧基乙烷（TEGDI）制备聚氨酯弹性体（PUE）。采用预聚物法，以TEGDI或HDI、聚氧四亚甲基二醇（PTMG）和固化剂合成了聚氨酯弹性体。1，6-六亚甲基二异氰酸酯（HDI）也用作对照二异氰酸酯。由于TEGDI本身的柔性和较弱的相分离，TEGDI基聚氨酯弹性体表现出高度的软化性能。另一种基于TEGDI的PUE用聚（氧丙烯）二醇（PPG）或聚（己内酯）二醇（PCL）制备。这些基于TEGDI的PUE的微相分离结构与一般二异氰酸酯的PUE有很大不同，并且使PUE大大软化。(c)2005爱思唯尔有限公司保留所有权利。
A diisocyanate baring ether bonds, 1,2-bis(isocyanate)ethoxyethane (TEGDI), was used for the preparation of polyurethane elastomers (PUEs). The PUEs were synthesized with either TEGDI or HDI, poly(oxytetramethylene) glycol (PTMG), and curing agents by a prepolymer method. 1,6-Hexamethylene diisocyanate (HDI) was also used as a control diisocyanate. The TEGDI-based PUEs exhibited highly softened property on account of flexibility of TEGDI itself and weaker phase separation. Another TEGDI-based PUEs were prepared with either poly(oxypropylene) glycol (PPG) or poly (caprolactone) glycol (PCL). Microphase-separated structure of these TEGDI-based PUEs are quite different from those with general diisocyanates and the PUEs were made be greatly softened. (c) 2005 Elsevier Ltd.
