| 中文摘要: |
| 采用过氧化预辐射法将生产高分子特效膜残留下的废苯乙烯（St）与聚丙烯酸丁酯-丙烯酸（PBA-AA）接枝，制得PBA-AA/St接枝共聚物。比较了辐射法和化学法所制接枝共聚物的粘接性能，考察了St含量、丙烯酸丁酯（BA）/AA共聚物特性粘度、AA用量、BA和St预辐射剂量对接枝共聚物粘接性能的影响。结果表明，采用辐射法所制接枝共聚物的粘接性能优于化学法所制接枝共聚物的粘接性能；废St比纯St效果好；当St含量为33%、BA/AA共聚物特性粘度适中、AA用量为5.5份（BA用量固定为100份）、BA预辐射剂量为16.0kGy、St预辐射剂量为32.0kGy时，制得的接枝共聚物的粘接性能最为理想。 |
| 英文摘要: |
| 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. |
