At room temperature, polyether-polybasicalcohol, polyisocyanate and so on were used as mainly materials to synthesize a series of high-hardness polyether urethane 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。

This invention relates to glycerinoid polybasicalcohol compositions which are solid or liquid compositions composed of sorbitol and diglycol, 1,3-butanediol or 1,4-butanediol.
This paper discusses on the influence of different structures of isocyanate, different system of polyether-polybasicalcohol and different synthetic methods on polyurethane elastomers.
