One of the most striking features of polyvinyl alcohol is its solubility in water. Unlike many other polymers, PVA can dissolve in water at ambient temperatures, forming a viscous solution that can be manipulated for various applications. The degree of hydrolysis and molecular weight significantly influence the properties of PVA solutions, including the viscosity, clarity, and stability. PVA solutions are characterized by their excellent film-forming properties, which allow them to create thin, transparent films that are flexible and strong.
