Title:
PROCESS FOR PREPARING POLYROTAXANE HAVING BLOCKING GROUPS
Document Type and Number:
WIPO Patent Application WO/2013/147301
Kind Code:
A1
Abstract:
The present invention pertains to a process for preparing a polyrotaxane which comprises a cyclic molecule, a linear molecule which is clathrated in the cyclic molecule in a state such that the linear molecule is threaded through the cyclic molecule, and blocking groups which are located at both terminals of the linear molecule so as to prevent the disassociation of the cyclic molecule from the linear molecule. This process comprises reacting a linear molecule which is clathrated in a cyclic molecule and which has carboxyl groups at both terminals with an amino-containing blocking agent either in the absence of a solvent or in at least one organic solvent selected from the group consisting of aprotic amide solvents and aromatic hydrocarbons in the presence of 2.0 to 100 mol of a triazine-based amidating agent per mol of the carboxyl groups of the linear molecule to form blocking groups.
