摘　　要：通过三步反应设计构筑了一种具有双键结构的改性α-环糊精聚轮烷,由于α-环糊精可以在聚乙烯醇链上滑动,因此可以将其视作一种具有"滑轮"效应的交联剂,通过红外光谱、二维核磁共振光谱及X射线衍射等表征了其结构.将新型聚轮烷交联剂和传统交联剂N,N'-亚甲基双丙烯酰胺分别与丙烯酰胺交联共聚制备体膨颗粒,测定其溶胀性能和形变性能.吸水膨胀51 h后,聚轮烷交联剂制备的体膨颗粒吸水倍率为8.32,受到294.3 N的外力再撤消后,体膨颗粒未破碎且能恢复至原始状态,而传统交联剂制备的体膨颗粒吸水倍率为6.75,受到112.4 N的外力后,体膨颗粒发生破碎.表明由聚轮烷交联剂制备的体膨颗粒具有更大的膨胀倍率和更优异的形变性能.A kind of polyrotaxane with polymerizable double bonds was designed and prepared through three step reactions.Because theα-cyclodextrin can slide freely on the chain of polyvinyl alcohol,this polyrotaxane can be considered as a cross-linking agent with“pulley”effect.The structure of polyrotaxane was characterized by Fourier transform infrared spectrophotometer(FTIR),2D nuclear magnetic resonance(NMR),X-ray diffraction(XRD),and so on.The swelling grains were prepared by copolymerization of acrylamide with novel polyrotaxane cross-linking agent and ordinary cross-linking agent N,N′-methylenebisacrylamide individually.The swelling ability and deformability of swelling grains were also investigated.After swelling for 51 h,for swelling grain prepared by novel polyrotaxane cross-linker,the water absorption is 8.32.The swelling grain is not broken and can restore the original state after receiving and with drawing 294.3 N external force.But for swelling grain prepared by ordinary cross-linker,the water absorption is 6.75.The swelling grain is broken after receiving 112.4 N external force.The swelling ability and deformability of swelling grain prepared by the polyrotaxane cross-linking agent are better than those of grain prepared by the ordinary chemical cross-linking agent.
