摘要
The solid phase graft copolymerization of polypropylene (PP) andmethacrylic acid (MAA) was investigated. benzoyl peroxide(BPO) wasused as initia- tor. The influence of the reactive time,concentration of initiator and monomer on degree of graft and meltflow index of graft copolymer(PP-MAA) was discussed. The effect ofgraft copolymer on mechanical properties of The glass fibre (GF)reinforced PP composites was also Studied. It is proved that graftcopolymer could obviously Increase the interfacial adhesive strengthbetween PP and GF.
