    Application
    Poly(vinyl acetate), with an approximate molecular weight of 170,000, serves a vital role as a versatile polymer widely used in various applications. Its primary purpose is as an adhesive and binder in water-based or emulsion paints due to its leathery, colorless, and thermoplastic nature, which softens at low temperatures and maintains stability under light and oxygen exposure. The polymer consists of repeating acetoxyethylene units and demonstrates sensitivity to base hydrolysis, gradually transforming into polyvinyl alcohol and acetic acid under alkaline conditions. Furthermore, boron compounds like boric acid or borax can facilitate cross-linking within the polymer, resulting in tackifying precipitates or slime. This characteristic enhances its utility in drug delivery, hemodynamics, wound dressing, and coatings. Poly(vinyl acetate) is soluble in a variety of solvents, including acetone, benzene, and ethanol, which further expands its application potential.
