| Abstract: |
| A PBA-AA/St grafting copolymer was made by grafting the waste styrene（St）from the production of functionalized polymeric membrane to poly [butyl acrylate（BA）-acrylic acid（AA）] through peroxidation preirradiation. The bonding property of the radiation grafting copolymer was compared to that of the chemically grafting copolymer. The influence of St level，characteristic viscosity of BA-AA copolymer, AA level，preirradiation dose on the bonding property of the graft copolymer was investigated. The results showed that the radiation grafting copolymer was better than the chemically grafting copolymer in terms of the bonding property；the waste St was better than the raw St；the optimum bonding property of the graft copolymer was obtained when 33 wt% of St，BA-AA copolymer with appropriate characteristic viscosity，5.5 parts of AA（based on 100 parts of BA），16.0kGy of preirradiation dose to BA，32.0kGy of preirradiation dose to St were used. |
