采用三元乙丙橡胶接枝马来酸酐（MAH-g-EPDM）增容聚酰胺66（PA 66）/热液晶聚合物（TLCP）复合材料。在双螺杆挤出机上进行共混，然后进行注塑。研究了共混物的流变性能、动态力学性能、热性能、力学性能以及形态结构和红外光谱。流变学、DMA和FTIR测试结果表明，MAH-g-EPDM是PA 66/TLCP共混物的有效增容剂。力学性能测试结果表明，随着MAH-g-EPDM含量的增加，共混物的拉伸强度、拉伸伸长率和弯曲强度均有所提高，说明共混物可能具有较大的摩擦剪切力，这是由于基体与分散相界面的强粘结作用所致;随着MAH-g-EPDM含量的增加，PA 66的弯曲模量降低，这是由于MAH-g-EPDM的加入阻碍了PA 66晶相的发展。Polym.比较器：27：608-613，2006.© 2006年塑料工程师协会
Polyamide 66–thermal liquid crystalline polymer (PA66/TLCP) composites containing 10 wt% TLCP was compatibilized by ethylene–propylene–diene-grafted maleic anhydride terpolymer (MAH-g-EPDM). The blending was performed on a twin-screw extrusion, followed by an injection molding. The rheological, dynamic mechanical analysis (DMA), thermal, mechanical properties, as well as the morphology and FTIR spectra, of the blends were investigated and discussed. Rheological, DMA, and FTIR spectra results showed that MAH-g-EPDM is an effective compatibilizer for PA66/TLCP blends. The mechanical test indicated that the tensile strength, tensile elongation, and the bending strength of the blends were improved with the increase of the content of MAH-g-EPDM, which implied that the blends probably have a great frictional shear force, resulting from strong adhesion at the interface between the matrix and the dispersion phase; while the bending modulus was weakened with the increase of MAH-g-EPDM content, which is attributed to the development of the crystalline phase of PA66 hampered by adding MAH-g-EPDM.
