Modified Polyvinyl Alcohol (mPVA) represents a class of chemically or physically altered forms of polyvinyl alcohol (PVA) tailored to meet specific industrial and commercial needs. By modifying the base polymer, its properties can be optimized for enhanced performance in applications ranging from adhesives and coatings to biomedical devices and packaging. modified polyvinyl alcohol is a synthetic polymer derived from polyvinyl acetate (PVAc) through hydrolysis. It is water-soluble, biodegradable, and possesses excellent film-forming and adhesive properties. However, for some applications, unmodified PVA may fall short in areas such as thermal stability, mechanical strength, or compatibility with certain materials. This is where modifications come into play.
