Title:
METHOD FOR PRODUCING CROSSLINKED POLYMER OR SALT THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/024773
Kind Code:
A1
Abstract:
Provided is a crosslinked polymer or a salt thereof, which is useful for a binder component capable of suppressing the expansion degree of an electrode in a nonaqueous electrolyte secondary battery. As a method for producing the crosslinked polymer or a salt thereof, provided is a method comprising a polymerization step for polymerizing a non-crosslinking monomer composition containing a nitrogen-containing ethylenically unsaturated monomer and an ethylenically unsaturated carboxylic acid monomer by precipitation polymerization. The concentration of the non-crosslinking monomer composition in the polymerization step is 16-30 mass% of a polymerization reaction liquid.
