| abstract |
The present invention provides a material having a crosslinked polyrotaxane having a desired viscoelasticity without containing a solvent, particularly a material having a low stress range in terms of stress-strain characteristics, particularly viscoelastic, and a method for producing the same. The present invention relates to a material having a first polyrotaxane and a second polyrotaxane, wherein the first and second polyrotaxanes are crosslinked through the first and second cyclic molecules, And a stress of 50% strain of the material is 2.0 MPa or less. |
