摘　　要：研究了乙烯-醋酸乙烯共聚物(EVA)增容高密度聚乙烯(HDPE)和聚碳酸酯(PC)共混体系,讨论了EVA,PC对HDPE/PC共混合金性能的影响。结果表明:随PC用量的增加,HDPE/PC共混合金的熔体流动速率减小,缺口冲击强度增大,拉伸强度增大,维卡软化点变化不大。EVA能够改善合金体系的加工流动性,却明显降低了合金体系的力学性能。HDPE/PC/EVA plastic alloy was studied, EVA used as compatibilizer in the blends. The effects of EVA and PC on HDPE/PC alloy were discussed. The results show that MFR of HDPE/PC alloy is reduced, the impact strength and tensile strength is increased, and softening point has no remarkable changes with increasing the content of PC . The processing properties of the alloy are increased but its mechanical properties lose more or less when EVA is added.
