摘　　要：分别采用聚丙烯接枝马来酸酐(PP-g-MAH)和硬脂酸(ST)作为相容剂,通过熔融共混法制备了PA6/PP(聚酰胺6/聚丙烯)合金,研究相容剂用量对该合金性能的影响。结果表明,随着相容剂的增加,PA6/PP合金的吸水性和熔体流动速率下降,拉伸强度和缺口冲击强度先增大后减小。当PP-g-MAH和ST用量分别为PA6/PP合金的4.0%(质量分数,下同)和2.0%时,复合材料的综合性能更佳。Polyamide 6/polypropylene （PA6/PP） alloys were prepared by melt mixing using maleic anhydride grafted polypropylene （PP-g-MAH） and stearic acid （ST） as compatibilizer. The effects of compatibilizer content on the mechanical properties of PA6/PP were investigated. The results show that with the increase of compatibilizer con- tent, water absorption and melt flow rate of PA6/PP alloys decreases. And the tensile strength and notch impact strength increases firstly then decreases. When the mass ratio of PP-g-MAH and ST was 4.0% and 2.0;, respectively, the comprehensive per- formance of alloys possess better.
