摘要

Provide a method of manufacturing the same and a polyrotaxane present invention has not been developed yet, the main chain backbone consists essentially -Si-O-. Polyrotaxane having a durable oxygen permeability, heat resistance, chemical resistance, and environmental resistance and / or while having a viscoelastic and / or elastic, and provides a manufacturing method thereof. The method of manufacturing the same and a crosslinked polyrotaxane formed by crosslinking via a chemical bond with polyrotaxane and / or other polymers for the polyrotaxane. A polyrotaxane across step of blocking the opening of the cyclic molecule formed by the inclusion skewered shape by the linear molecule, formed by placing a blocking group the cyclic molecules are not eliminated, the invention is direct the main chain skeleton consists essentially -Si-O-, chain-like molecules, provides the above polyrotaxane.
