The present invention provides a crosslinked polymer composition exhibiting significantly improved elongation at break over conventional ones, and a polymer composition and a polyrotaxane, each of which can be used as a raw material of the crosslinked polymer composition. The polyrotaxane contains a linear molecule, a cyclic molecule, and a blocking group, wherein the cyclic molecule has a hydrosilyl group. The polymer composition contains the polyrotaxane and a polymer, wherein the polymer has a double bond on at least either a main chain or a side chain. The crosslinked polymer composition is produced by crosslinking of the polymer composition through chemical reaction between the hydrosilyl group of the cyclic molecule and the double bond of the polymer.

Polyrotaxane, polymer composition, crosslinked polymer composition, and production method therefor

The present invention provides isolated nanosheets each of which includes a plurality of pseudo-polyrotaxanes and which are easily isolated without adhering to each other. The present invention provides an isolated nanosheet including a plurality of pseudo-polyrotaxanes each having one or more first cyclic molecules and a linear molecule included in a cavity or cavities of the first cyclic molecules in a skewered manner, wherein the linear molecules include, as part thereof, first linear molecules each having an ionizable group that ionizes in water or an aqueous solution.
