摘　　要：研究了线性低密度聚乙烯(LLDPE)/聚丙烯(PPR)共混体系、高密度聚乙烯(HDPE)/聚丙烯(PPR)共混体系、超高分子量聚乙烯(UHMWPE)/聚丙烯(PPR)共混体系的力学性能和熔体流动速率。结果表明,UHMWPE的增韧改性效果最好,在UHMWPE的含量为15%时体系的综合力学性能最好。LLDPE的增韧改性效果次之,HDPE的最差。The mechanical properties and the melting flow rate of LLDPE/PPR, HDPE/PPR and UHMWPE/PPR were studied. The result showed that UHMWPE had the best toughening effect. It was found the composite system had excellent mechanical properties when UHMWPE content was 15%. HDPE had the lowest effect.
