ADHESIVE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2021/256416
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive composition that is durable against a liquid electrolyte and that has improved hot adhesion characteristics. This adhesive composition is characterized by containing an acid-modified polymer obtained by acid modification of a polymer using an unsaturated carboxylic acid anhydride, the polymer being capable of radical graft reaction, and a crosslinking agent, the melting point of the acid-modified polymer being 4.5-15°C lower than the melting point of the polymer before acid modification.
