英文摘要	通过葫芦[6]脲(CB[6])与聚[4-乙烯基-溴(N-正丁基)吡啶季铵盐](P4VBuBr,2)在水溶液中于室温下进行超分子自组装,得到一类超分子聚合物--准聚轮烷.通过1H-NMR、IR、元素分析对其结构进行了表征,证实CB[6]位于2的侧基脂肪链上,通过非共价键与2结合,并且CB[6]与2重复单元的结合摩尔比分别为0.28:1、0.2:1、0.1:1;通过X-射线粉末衍射(XRD)、热重分析(TGA)、紫外-可见吸收(UV-Vis)对其性质进行了研究,证实了准聚轮烷比相应的聚合物2有更高的热稳定性、更强的UV-Vis吸收以及较高的结晶能力;热分解温度随着准轮烷中CB[6]含量的增加而逐渐提高;NaBr是准聚轮烷的优良的沉淀剂.; A kind of pseudopolyrotaxanes was prepared by supramolecular self-assembly of poly (4-vinyl-N-n-butylpyridinium bromide) (P4VBuBr 2) with cucurbituril[6] (CB[6]) in water at room temperature. The chemical structure of pseudopolyrotaxanes was confirmed by H-1-NMR, IR spectras and elemental analysis: CB[6] beads are localized aliphatic chain in side-chain of 2, and combine N+ by non-covalent bonds. Molar ratio of CB[6] to the repeat unit of 2 is 0.28 : 1, 0.2 : 1 and 0.1 : L The properties of these pseudopolyrotaxanes were studied by thermogravimetry analysis(TGA), UV-Vis, X-ray powder diffraction (XRD) measurements and adding NaBr to the solution of the pesodupolyrotaxanes. The results show that pseudopolyrotaxanes have higher thermal stability, stronger absorption band and higher crystallizability than the parent polymers. The thermal decomposition temperature of pesudopolyrotaxanes increases with increasing the amount of CB [6] threaded on the polymer. NaBr is a good precipitating agent for the pesudopolyrotaxanes.; 教育部留学回国人员科研启动基金; 山东大学校科研和教改项目; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000231546500004&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 9; 4; 491-495
