    Abstract: The invention provides an industrially advantageous method for the production of hydroxyalkylated polyrotaxanes. The method of producing hydroxyalkylated polyrotaxane includes reacting a polyrotaxane with a cyclic ether represented by Formula (1) in the presence of water and an organic base, wherein the polyrotaxane includes hydroxyl group-containing cyclic molecules, a linear molecule threaded through the cyclic molecules to form a clathrate, and blocking groups at both ends of the linear molecule to prevent the separation of the cyclic molecules from the linear molecule.

    Abstract: The present invention provides a polyrotaxane having high durability and in particular, high hydrolysis resistance, and a method for producing said polyrotaxane. The present invention provides a polyrotaxane obtained by disposing blocking groups on both ends of a pseudopolyrotaxane so that an annular molecule cannot be displaced, said pseudopolyrotaxane being obtained by forming a clathrate by piercing the opening of the cyclic molecule with a linear molecule, said polyrotaxane being characterized in that the cyclic molecule has a substituent represented by formula I (in formula I, R1 represents a group such as —CH3 and —CH2—CH3, R2 represents H or a group such as —CH3, and n is the apparent degree of polymerization of a polyalkylene oxide chain or a derivative thereof added to the cyclic molecule, the value of n being 1.1 to 10.0).
