In the review of PVA characteristics as an industrial material, the following three factors are important: molecular weight, degree of hydrolysis, and its solubility. These properties affect the function of PVA in a variety of applications. More molar mass PVA usually has good film effectiveness and adhesion properties whereas varying hydrolysis levels determines the degree of dissociation as well as the ability to blend with other substances. These characteristics help industries to use the right PVA that is fit for their needs in a given process in order to improve performance and increase efficiency.
