摘要： 用4种热致液晶聚合物分别与聚丙烯、聚对苯二甲酸丁二酯、聚碳酸酯、聚醚砜和聚砜搭配,在各聚合物对的"加工窗口"温度范围内熔融共混并挤塑得到6种共混物。藉流变仪、扫描电子显微镜、偏光显微镜、动态力学谱仪等重点研究了原位复合材料中微纤结构的形成,组分特性、熔体粘度、挤塑温度和浓度等因素对各向异性结构形成的贡献,以及液晶聚合物对聚合物结晶的诱导作用和两相间的相互作用。

Abstract: From four thermotropic liquid crystalline polymers (TLCP) and polypropylene, poly(butylene terephthalate), polycarbonate,polyethersulfone and polysulfone, six polyblends containing TLCP were melt blended and extruded in the temperature range of respective "processing window". With the help of rheometry, scanning electron microscopy, polarized light microscopy and dynamic mechanical spectroscopy,the microstructure formation,and contribution of component characteristics, melt viscosity, extrusion temperature and concentration to the anisotropic microstructure formation and fibril-in-duced crystallization of matrix polymer and interphasial interaction were investigated.
Key words: liquid crystalline polymer, polymer blend, in-situ composite, thermoplastics
