摘　　要：以马来酸二丁酯(DBM)为单体,在实验室采用熔融接枝方法制备聚丙烯接枝马来酸二丁酯(PP-g-DBM),并通过熔融共混挤出制备了PA6/PP/PP-g-DBM共混物和PA6/PP/PP-g-MAH的共混物,研究了不同种类相容剂及相容剂用量,对PA6/PP共混物力学性能、熔体流动速率、流变性能的影响。结果表明:PP-g-DBM较PP-g-MAH,是更好的相容剂和增塑剂。少量PP-g-MAH较PP-g-DBM对材料的力学性能有增强效果。As a monomer, the melting graft reaction between Dibutyl Baleate （DBM） and polypropylene （PP） was studied,and the PA6/PP/PP-g-DBM blend was made. Then the effect of different kind compatilizer and compatibilizer contents on PA6/PP blend were studied. Research had been showed that PP-g-DBM was better than PP-g-MAH as the compatibility agent and plasticizer. A small amount of PP-g-MAH could improve the mechanical property of the blend better than PP-g- DBM.
