摘要：

The synthesis and structure of graft polyrotaxane, a novel class of graft copolymer possessing mobile graft chains, is described. Poly(tetrahydrofuran) was bound to the axle components of pseudo[2]rotaxane as the graft chain by a grafting-onto method to afford the corresponding graft polyrotaxane (see picture). N-Acetylation of the ammonium moieties lead to an increase in the dynamic radius of the graft polyrotaxane. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
