Grafting of glycidyl methylacrylate(GMA) on chlorinated polypropylene(CPP) by melt grafting process was carried out with benzoperoxide(BPO) as the initiator,and the structure of the purified product was characterized by FTIR.Effects of reaction temperature,amount of BPO and monomer on the adhesion properties of the modified CPP were studied.The optimized reaction conditions are:reaction temperature 140℃,ω(BPO)=0.4%,ω(GMA)>6%,and n(St)/n(GMA)=1.4.The experimental results show that the chlorinated polypropylene has a better adhesion property for aluminum and the value of peel strength reaches 2 449.92 N/m.
