Modified polyvinyl alcohol (PVA) refers to a class of PVA derivatives that have been chemically altered to enhance or impart specific properties for specialized applications. While PVA itself is known for its solubility in water, biodegradability, and ability to form films, its base properties can be limiting in certain applications. To overcome these limitations, PVA can be modified in various ways, such as through chemical crosslinking, graft copolymerization, blending with other polymers, or by introducing functional groups. These modifications allow PVA to be used in a broader range of in

Polyvinyl alcohol (PVA) is a synthetic polymer widely used in various applications due to its unique properties, including water solubility, biodegradability, and film-forming abilities. The polymer itself is derived from polyvinyl acetate (PVAc), which undergoes hydrolysis to produce PVA. The degree of hydrolysis of PVA is a crucial factor that influences its properties and applications. In this context, “partially hydrolyzed polyvinyl alcohol” refers to PVA that has undergone incomplete hydrolysis, resulting in a polymer with a lower degree of hydrolysis compared to fully hydrolyzed PVA.
