Compositions comprising epoxy resins containing one or more mesogenic or rodlike moieties per molecule are cured with polyamines containing one or more mesogenic or rodlike moieties per molecule. These curable compositions can be oriented by the application of an electric field or magnetic field or drawing and/or shear flow prior to and/or during curing. The resultant cured products exhibit an improvement in one or more physical and/or mechanical and/or thermal properties as compared to a like epoxy resin system which does not contain any mesogenic or rodlike moieties.
由分子中含有一个或多个介基或棒状分子的环氧
树脂组成的组合物与分子中含有一个或多个介基或棒状分子的
多胺一起固化。在固化前和/或固化过程中,可通过施加电场或磁场或拉伸和/或剪切流使这些固化组合物定向。与不含任何介基或棒状基团的同类环氧
树脂体系相比,固化后的产品在一种或多种物理和/或机械和/或热性能方面均有改善。
