Itaconic acid-vinyl acetate-vinyl alcohol copolymer is a functional water-soluble polymer containing hydroxyl, carboxyl, and acetate groups. It is mainly used as a polymer additive, adhesive modifier, coating additive, textile auxiliary, paper processing aid, dispersant, and water-retention agent. It can improve adhesion, film-forming properties, flexibility, and compatibility in polymer formulations.
