| 摘 要： | 在热致液晶共聚酯（ＬＣＰ）与聚丙烯（ＰＰ）的共混体系中引入相容剂（接枝共聚物ＭＡＨ—ｇ－ＰＰ），借助热台偏光显微镜、扫描电镜、差示扫描量热仪、流变仪等方法研究了相容剂对ＰＰ／ＬＣＰ原位复合材料的微观结构和界面性能、结晶行为、流变行为以及力学性能的影响．结果表明：添加相容剂后，基体中的ＬＣＰ微纤分散更均匀，ＬＣＰ微纤长径比Ｌ／Ｄ增大．ＰＰ和ＬＣＰ两相之间有较好的粘连，促进了共混体的结晶，改善了ＰＰ／ＬＣＰ原位复合材料的力学性能．

| Abstract: | The compatibilizer (graft copolymer MAH - PP) was introduced into the blends of polypropylene with thermotropic liquid crystalline copolyester. The effect of compatibilizer on morphological structure and interfacial properties, crystalization behaviour, rheological behaviour and mechanical properties of PP/LCP in situ composite material by means of polarizing microscope, scanning electron microscope, differential scanning calorimetry and rheometer were investigated. The results showed that the LCP fibrils in matrix dispersed more uniformly, L/D ratio of the LCP fibrils rised, adhesions between two phases of PP and LCP, crystalization of the blends and mechanical properties of PP/LCP in situ composite material were improved after adding the compatibilizer. |
