Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer known for its excellent film-forming, emulsifying, and adhesive properties. Over the years, researchers and manufacturers have developed modified versions of PVA to enhance its properties and expand its applications. Modified PVA materials are tailored to meet specific requirements in diverse industries, including pharmaceuticals, packaging, textiles, and environmental engineering. This article explores the characteristics, modifications, applications, and environmental significance of Modified polyvinyl alcohol.Polyvinyl alcohol is a unique polymer primarily derived from the hydrolysis of polyvinyl acetate. Its base properties include:
