摘　　要： 用固相接枝法接枝合成了聚丙烯(PP)与甲基丙烯酸甲酯(MMA)/马来酸酐(MAH)/丙烯酸丁酯(BA)的多单体接枝共聚物(GPP),将其应用于废聚丙烯(RPP)/稻糠(RC)复合体系,研究了接枝共聚物对体系的力学性能、微观形态、热性能的影响。结果表明,在RPP/RC复合体系中加入固相接枝共聚物,可有效提高复合材料的拉伸强度、弯曲强度、弯曲模量和维卡软化点。 The multi-monomer graft copolymer of PP with maleic anhydride (MAH)/methyl methacrylate (MMA)/butyl acrylate (BA) was synthesized by solid-phase graft copolymerization, and the graft copolymer was then used as interfacial modifier to recycled PP (RPP)/ rice chaff(RC) composites. The effect of the graft copolymer on the mechanical properties, micro-structure and heat resistance of RPP/RC composite was studied. The results showed that the addition of the graft copolymer into RPP/RC could effectively improve the tensile strength, bending strength, bending modulus and Vicat softening point of the composites.
