一种新型嵌段共聚物的物理性能

Physical Properties of a New Kind of Block Copolymers

研究了由低相对分子质量聚砜链段与刚性棒状链段组成的嵌段共聚物的物理性能。它们都具有液晶性，可溶解于氟仿－对氯苯酚混合溶剂，不溶于氯仿。且都有一个玻璃化转变温度和一个熔点。还对这些嵌段聚合物和刚性棒状液晶聚合物的性能进行了比较。

The physical properties of four block copolymers,which containing polysulfone chain and ri8id rod chain,were studied.They could form liquid crystalline state,and dissolve in chloroform/ p-chlorophenol solvent.The differential scanning calorimetry results showed that these block copolymers all had a glass transition temperature and a melt point.Their properties were compared with some liquid crystalline polymers.
