| Research Abstract |
Polyurethanes crosslinked by an eight-figure shaped azobis(crown ether) and a necklace shaped polyrotaxane, which consists of 12 cyclodextrins and poly(ethylene oxide), were synthesized and characterized. The polyurethane crosslinked by the eight-figure shaped bis(crown ether) showed high elongation performance because of sliding effect arisen from the rotaxane structure. Introduction of the relatively-rigid polyrotaxane as the crosslink points to the polyurethane structure resulted in keeping of the elastic performance in high temperature region.
