<p>Disclosed are a material that has a cross-linked polyrotaxane and that has desired viscoelastic properties, specifically a desired loss tangent, without containing a solvent, and a method for producing same: a material having a first polyrotaxane and a second polyrotaxane, wherein the first polyrotaxane comprises first blocking groups being disposed at both ends of a first pseudo-polyrotaxane-formed from the opening of a first circular molecule being enclathrated by being skewered by a first linear chain molecule-in a manner so that the first circular molecule does not detach; the second polyrotaxane comprises second blocking groups being disposed at both ends of a second pseudo-polyrotaxane-formed from the opening of a second circular molecule being enclathrated by being skewered by a second linear chain molecule-in a manner so that the second circular molecule does not detach; said first and second polyrotaxane are formed from crosslinking with the first and second circular molecules therebetween; said material is solvent-free; and the material has a loss tangent (tand) of at least 0.1 at 25°C and 11 Hz.</p> |
