摘要
用液化改性MDI、聚醚多元醇为原料 ,ED或BD为扩链剂 ,合成一系列不同硬段结构的聚氨酯弹性体 ,并对这些聚合物进行了红外结构、力学性能以及溶解性能的研究 ,并就其现象进行了理论上的分析。
Using polyether-polyol liquification modified MDI as materials,using ED or BD as chain extenders,we synthesized polyether/liquified modified MDI-based polyurethane elastomers.The structure and mechanical properties of the elastomers were studied.And also the hydrolysis measurements of the elastomers were studied.And the phenomenon were analysized with theory.
