Acrylic copolymer containing dimethylaminoethyl methacrylate, butyl acrylate, and vinyl acetate units. It is mainly used as a functional polymer intermediate and specialty polymer additive. Applications include pharmaceutical coating materials, controlled-release formulations, film-forming agents, adhesive systems, textile auxiliaries, surface modifiers, and water-based polymer technologies. The tertiary amino groups provide pH-responsive properties and enhance polymer functionality.
