The acrylic acid ester grafting chlorinated propylene(ACRYL-g-CPP) was produced by technique of solution grafting copolymerization in presence of radical initiator. The experience result shows that the coating made by the ACRYL-g-CPP have good adhesion force, plexibility, hardness. The conditions of the solution grafting copolymerization are: 80℃,2. 5-3. 0 h,CPP(25%wt) : acrylic acid : methyl methylacrylic : butyl a-crylic =150 : 7 : 35 : 15(wt).
