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.
A polyrotaxane comprising a linear molecule, a cyclic molecule enclosing the linear molecule such that the cyclic molecule is skewered with the linear molecule, and blocking groups disposed at both ends of the linear molecule for preventing removal of the cyclic molecule, characterized in that:
