中文摘要: 为开发纤维素基吸油材料,以棉浆粕为基材、甲基丙烯酸丁酯(BMA)为单体、乙二醇二甲基丙烯酸酯为交联剂,采用悬浮接枝聚合法合成了BMA接枝纤维素的聚合物。采用红外光谱(FT-IR)、X射线衍射(XRD)、扫描电镜(SEM)、热重(TG)、差热(DSC)等手段对所得吸油材料结构进行了表征。考察了引发剂的种类及用量、接枝单体及交联剂用量、反应温度、反应时间等因素对BMA接枝纤维素聚合物的接枝聚合反应性能及吸油性能的影响。结果表明:当m(棉浆粕)∶m(K2S2O8)∶m(BMA)∶m(乙二醇二甲基丙烯酸酯)=1∶0.025∶1.5∶0.005,75 ℃下恒温反应6 h,合成的BMA接枝纤维素的接枝率最高(36.2%),均聚物含量相对较低(5.8%),且吸油性能优良。

Abstract:The poly(BMA) grafted cellulose copolymer was synthesized with the aim of producing cellulose based oil absorption resins from butyl methacrylate modified cotton pulp(cellulose) by suspension graft copolymerization using glycol propane diacrylate as crosslinker. The structure of the graft copolymer was characterized by means of FT-IR, XRD, SEM, TG, DSC, etc. The effects of reaction conditions, such as kinds and amounts of initiator, weight ratio of monomer and crosslinker , reaction temperature, reaction time etc,on the graft copolymerization and oil pick up ability of the poly(BMA) grafted cellulose copolymer were examined.The optimized reaction conditions for the synthesis of cellulose BMA graft copolymer were : m(Cotton pulp)∶m(K2S2O8 initiator)∶m (Butyl methacrylate graft monomer)∶m(Glycol propane diacrylate crosslinker)= 1∶0.025∶1.5∶0.005,75 ℃,and 6 h. Under the above conditions, the graft yield reached 36.2%, homopolymer content was 5.8%, and oil pick up abilities were choiced.
