自1978年合成热致液晶侧链聚合物以来，这一领域发展迅速(参考文献[9])。此后不久，由液晶侧链聚合物交联合成的液晶弹性体领域增长缓慢，直到最近才开始对液晶弹性体的动态物理性能进行实验研究。这种情况在不久的将来有望改变，因为液晶单晶弹性体的合成已经被报道，这是固体物理中单晶的类似物，从而使用各种动态技术研究表征良好的宏观样品成为可能，包括光散射、超声波吸收、机电效应等。
After thermotropic liquid-crystalline side-chain polymers have been synthesized first I) in 1978, this field has been growing rapidly (compare, eg, refs.’9’) for reviews).The field of liquid-crystalline elastomers, which had been synthesized shortly thereafter 4, by crosslinking liquid-crystalline side-chain polymers, has been growing much more slowly5-*) and only re~ ently~~~~) the experimental investigation of the dynamic physical properties of liquid-crystalline elastomers has started. This situation can be expected to change in the near future, because the synthesis of liquid single crystal elastomers (LSCE’s), the analogue of single crystals in solid-state physics, has been reported 11, 12), thus making it possible to investigate well characterized macroscopic samples by various dynamic techniques including light scattering, ultrasound absorption, electromechanical effects, etc.
