| 摘要 |
A material combining properties possessed by crosslinked polymers with stretchability or viscoelasticity. The material comprises a polyrotaxane and a polymer, wherein the polyrotaxane comprises cyclic molecules, a linear molecule which pierces the cyclic molecules to form a clathrate therewith, a nd blocking groups disposed respectively at both ends of the linear molecule so as to prevent the cyclic molecules from separating from the linear molecule, and the polyrotaxane has been bonded to part or all of the polymer through t he cyclic molecules.
