摘要
在双螺杆挤出机上采用共混挤出的方法制备了苯乙烯-乙烯-丁二烯-苯乙烯嵌段共聚物(SEBS)和马来酸酐接枝苯乙烯-乙烯-丁二烯-苯乙烯嵌段共聚物(SEBS-g-MAH)增韧的聚苯醚(PPO)/聚酰胺66(PA66)合金。通过力学性能测试、扫描电子显微镜观察和吸水性实验,研究了SEBS和SEBS-g-MAH及其含量对PPO/PA66合金性能的影响。结果表明,SEBS-g-MAH增韧PPO/PA66合金体系的力学性能较好,吸水率较小。
Alloys of polystyrene oxide (PPO) and polyamide 66 (PA66) were prepared via twin-screw extrusion and toughened with stytene-ethylene-butadiene-styrene block copolymer (SEBS) and maleic anhydride grafted styrene-ethylene-butadiene-styrene block copolymer(SEBS-g-MAH). Effects of SEBS and SEBS-g-MAH on properties of PPO/PA66 alloys were studied through mechanical property test, scanning electron microscopy(SEM), and water absorption. It showed that the toughness of PPO/PA66 alloys with SEBS-g-MAH was improved obviously, meanwhile its water absorption decreased.
