| 摘 要： | 使2.2-(4’-羟基苯基)丙烷(双酚A)与环氧氯丙烷反应制得了带端羟基的酚氧树脂(HBA),将其与蓖麻油共混,用2.4-甲苯二异氰酸酯(TDI)作固化剂,制得了一系列交联聚氨酯。DSC和DMA测试结果表明,这种聚氨酯只有一个T_g。改变NCO/OH摩尔比及HBA/(HBA 蓖麻油)比可制得具有较好阻尼性能的聚氨酯材料。

| Abstract: | The hydroxy-teminated phenoxy resin (HBA) was prepared by reaction of biphenol-Awith epichlorohydrin. HBA was mixed with castor oil and reacted with toluene diisocyanategiving polyurethane. The mechnical and dynamic mechanical properties of the polyurethanewere investigated in various composition. The polyuretheane obtained has a single T_g. Underoptimum content of HBA and NCO/OH ratio, a series of polyurethanes with excellent dam-ping properties have been obtained. |
