摘要
通过加入液晶聚酯酰胺和聚碳酸酯的多嵌段共聚物，可以有效地降低基体聚碳酸酯的玻璃化转变温度，提高热致液晶高分子ＰＥＴ／６０ＰＨＢ与聚碳酸酯原位复合材料的相容性。随嵌段共聚物含量的增加，共混物拉伸强度有所提高，拉伸模量提高了１５％，同时，冲击强度也得到了增长。通过扫描电镜（ＳＥＭ）的观察发现，嵌段共聚物的加入改进了共混体系中两相间界面粘合。
The compatibility of the insitu composite of Polycarbonate(PC) and liquid crystalline copolyester can be improved by adding the multiblock copolymer prepared from PC and LC copolyesteramide oligomer. The mechanical properties of blends are increased when increasing the adding amount of block copolymer. Through the observation of SEM it can be found that the deformation of LC particles can be improved by the block copolymer and the interfacial adhesive becomes better.
