The liquid crystalline field of the polymers could be well kept at room temperature and the initial decomposition temperature of all the polymers was higher than the clearing point 所有聚合物的熔点都非常低,表明合成的一系列液晶聚合物非常容易进入液晶态,并且液晶场能够很好地保存到室温。

Structures of the camp fibers were also discussed . the results showed that the hydrogen bonding between the pva and caa damaged the regularity of crystalline field and the crystallinity of the fibers reduced . the cluster structures of each phase in the blend were changed and movement of the molecular chain segment was reduced 对camp纤维结构的研究表明, pva与丙烯酸-丙烯酰胺共聚物( caa )共混后,大分子间的氢键作用破坏了pva晶区结构的规整性,导致pva在camp纤维中的结晶性明显减弱;两种共混组分的聚集态结构发生变化,大分子链段运动受到影响。
