Polyrotaxanes and pseudopolyrotaxanes of polyamides and cucurbituril 1Dedicated to Professor Hartwig Höcker on occasion of his 60th birthday. 1

Pseudopolyrotaxanes and polyrotaxanes of polyamide and the macrocycle cucurbituril are synthesized easily by interfacial polycondensation. With different diammonium ions and diacid chlorides a great variety of poly(amide rotaxane)s is obtained. The structure of the diacid chloride influences the possible motion of cucurbituril on the polymer chain. First attempts to characterize these polyrotaxanes using IR, DTA, 1 H-NMR and elemental analyses are reported.
