| 摘 要： | The solid phase graft copolymerization of polypropylene (PP) and methacrylic acid (MAA) was investigated. Benzoyl peroxide (BPO) was used as initiator. The influence of the reactive time, concentratiom of initiator and monomer on degree of graft and melt flow index of graft copolymer (PP—MAA) was discussed. The effect of graft copolymer on mechanical properties of the glass fibre (GF) reinforced PP composites was also studied. It is proved that graft copolymer could obviously increase the interfacial adhesive strength between PP and GF.
