Title:
METHOD FOR PRODUCING CYANOETHYL GROUP-CONTAINING POLYMER
Document Type and Number:
WIPO Patent Application WO/2023/191430
Kind Code:
A1
Abstract:
The present invention relates to a method for producing a cyanoethyl group-containing polymer, the method comprising: a step for preparing a base catalyst aqueous solution by dissolving a base catalyst in an aqueous solvent; a step for preparing a dispersion of a polymer containing a hydroxyl group by adding a solid-state polymer containing a hydroxyl group to the aqueous solution of the base catalyst; and a step for introducing a cyanoethyl group-introducing precursor into the polymer dispersion and introducing a cyanoethyl group into a polymer containing a hydroxyl group through a cyanoethylation reaction.
