It is well established that polymer gels are classified into two groups : physical and chemical gels. We have recently developed a novel kind of gel different from the physical and chemical gels, slide-ring gel or topological gel, based on supramolecular architecture with topological characteristics. In the slide-ring gel, the polymer chains with bulky end groups are neither covalently cross-linked like chemical gels nor attractively interacted like physical gels, but are topologically interlocked by figure-of-eight cross-links. In the present work, we confirmed the pulley effect of the topological gel by measuring the stress-strain curve, small angle neutron scattering, quasi-elastic light scattering and so on.
