Title:
METHOD FOR CLEAVING COORDINATE BOND OF COMPLEXED POLYMER
Document Type and Number:
WIPO Patent Application WO/2022/049962
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method whereby crosslinks of a polymer can be easily eliminated.
A solution to the problem is a method for cleaving coordinate bonds of a complexed polymer which comprises at least one polymer chain and a plurality of nitrogen- and/or phosphorus-containing functional groups capable of forming coordinate bonds and bonded to the polymer chain and in which the nitrogen- and/or phosphorus-containing functional groups capable of forming coordinate bonds have combined with each other through coordinate bonds via a metal ion, the method being characterized by dissolving the complexed polymer in a solvent containing a free ligand, thereby cleaving the coordinate bonds.
