摘要：
A series of polymeric ''sanidic'' materials were investigated and a number of criteria developed which must be fulfilled in order to classify these materials as liquid crystalline. By a combination of electron diffraction and high-resolution imaging, the biaxial phase is shown to consist of poorly developed microcrystals embedded in a Liquid-Like amorphous matrix. Only some materials are able to form a liquid crystalline phase at higher temperatures, but this phase is uniaxial.
