摘要(Abstract)：
本文以聚四氢呋响(PTMG)、4,4′-二苯基甲烷二异氰酸酯(MDI)和1,4-丁二醇(BD)为原料,采用一步法合成聚氨酯样品,用DDV-Ⅱ动态粘弹仪测定了样品的动态力学图谱.首次建立了一套利用动态力学图谱计算聚氨酯松弛活化能的方法,并用活化能大小定量地表征了聚氨酯的微相离结构.
By using of the Reaction Injection Molding method, the samples of RPU(reaction polyurethane) were synthesized from polytetramethyleneoxide,4,4 diphenylenemethane diisocyanate and 1,4-butanediol, and tested on dynamic analysis instrument DDV-II.- A new method for calculating the active energy of RPU was established for the first time. The active energy datas calculated by the new method were used to analyse the microphase separation degree of the RPU samples.
