At room temperature, polyether-polybasic alcohol, polyisocyanate and so on were used as mainly materials to synthesize a series of high-hardness polyetherurethane elastomers.
在室温下，选用聚醚多元醇，多异氰酸酯等材料，合成了一系列高硬度聚氨酯弹性体。

In the experiment, di-isocyanate, polyether diol and a hydrophilic chain-extender were used to synthesize aqueous urethane.
实验采用二异氰酸酯与聚醚二元醇、亲水扩链剂反应合成水性聚氨酯。

Lastly, of course, the main reaction of interest is the formation of urethane groups by reaction of isocyanate groups and hydroxy - groups of the polyester or polyether.
