Used as a functional polymer intermediate and water-soluble copolymer material. It is applied in coatings, adhesives, textile auxiliaries, paper treatment agents, polymer modification, and formulation systems requiring ammonium carboxylate functional groups. It can provide adhesion improvement, film-forming properties, and compatibility enhancement in aqueous polymer systems.
