摘要
对聚砜（ＰＳＵ）／聚碳酸酯（ＰＣ）／热致液晶聚合物（ＴＬＣＰ）共混体系的流变性及形态进行了研究。结果表明，ＰＳＵ／ＴＬＣＰ＝９５／５、ＰＳＵ／ＰＣ＝７０／３０、ＰＳＵ／ＰＣ／ＴＬＣＰ＝６６．５／２８．５／５三种共混物的表观粘度均比ＰＳＵ的表观粘度低很多，且ＰＳＵ／ＰＣ／ＴＬＣＰ共混物的表观粘度也较ＰＳＵ／ＰＣ的有所下降。形态研究表明，ＰＳＵ与ＰＣ、ＴＬＣＰ具有部分相容性，ＴＬＣＰ以不规则的颗粒状分散在ＰＳＵ／ＰＣ基质中。
The rheology and morphology behaviors of blend of polysulphone (PSU)/polycarbonate(PC)/thermoropic liquid crystalline polymer(TLCP)have been studied.The results show that the viscosities of PSU/TLCP=95/5,PSU/PC=70/30,PSU/PC/TLCP=66.5/28.5/5 are lower than that of PSU,and the visosity of PSU/PC/TLCP is the smallest.The morphology show that the blends of PSU andPC or TLCP have partial miscibility, and TLCP disperses its irregular grains in PSU or PC matix [WT5”HZ〗
