将单取代烯烃引入到β-环糊精(β-CD)外腔,使之成为空腔内外均具亲油性、且含有可聚合双键的活性大单体(β-CD-A)；选取软单体丙烯酸十六酯(HDA)、硬单体苯乙烯与β-CD-A 配伍,经悬浮共聚制备出了含环糊精基三元共聚高吸油树脂—PCDHS.论文探讨了β-CD-A 用量、软硬单体配比、交联剂用量等对树脂吸油性能的影响,并确定了最佳工艺.结果表明,PCDHS 高吸油树脂对汽油、甲苯、氯仿和四氯化碳的吸油倍数分别达到25．6,37．2,45．3和54．6 g/g,保油率高达90％以上.
Introducing the mono substituted olefin to the external cavity,theβ-cyclodextrin derivative became a lipophilic active macromerβ-CD-A containing polymerizable bounds.Selection of soft monomer hexadecyl acry-late (HDA),and hard monomer styrene andβ-CD-A,the suspension copolymerization prepared copolymer high oil absorption resin PCDHS with cyclodextrin based three component copolymer.The impact ofβ-CD-A dosage, the ratio of soft/hard monomer,crosslinking agent on the properties of resins,and determine the best process. Were discussed in this paper.The results showed that the oil absorption ratio of PCDHS,the high oil absorbing resin on gasoline,toluene,chloroform and CCl4 were respectively 25.6,37.2,45.3 and 54.6 g/g,the oil reten-tion rate is as high as 90%.
