Title:
POLYROTAXANE HAVING SUBSTITUENT HAVING POLYALKYLENE OXIDE CHAIN OR DERIVATIVE THEREOF IN CYCLIC MOLECULE, AND METHOD FOR PRODUCING SAID POLYROTAXANE
Document Type and Number:
WIPO Patent Application WO/2018/225704
Kind Code:
A1
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).
