摘　　要：液晶离聚物(liquid crystalline ionomers,LCIs)是一种具有液晶性能的离聚物,也可以说是带有离子基团的液晶聚合物。将液晶离聚物与其它热塑性聚合物熔融共混时,其既能起到液晶聚合物的高模量、高强度作用,同时也具有离子的增容剂作用。本文论述了液晶离聚物在共混体系中的研究进展。按照液晶离聚物所含离子的不同,论述了含有—COOH,—SO3H和N+的液晶离聚物对共混体系的增容和增强作用。考察了液晶离聚物对共混体系热力学性能、形态结构和力学性能的影响。The liquid crystalline ionomers （LCIs） is the liquid crystalline polymer with ionic groups. The interest arises from two advantages of blending LCI with thermoplastics polymer. First, the LCIs can exhibit high modulus, strength. Second, ionic group of LCIs can compatibilize between LCIs and thermoplastics polymer. In this paper, progress on developing of blends system containing liquid crystalline ionomers （LCIs） was reviewed. According to the different group --COOH, --SO3H and ≡N^＋ ionomer of LCIs, effect of LCIs on compatibilization and intension of blends was briefly introduced. We investigated effect of LCIs on the thermal behavior, morphology, and mechanical property of blends.
