Poly(vinyl alcohol), MW 133,000, 99% hydrolyzed, is a high-molecular-weight PVA polymer supplied for research, formulation, film-forming, coating, adhesive, binder, and polymer processing applications. This highly hydrolyzed grade is commonly selected for work where water interaction, hydrogen bonding, film strength, and polymer viscosity are important formulation variables.
Synonyms and related names: PVA; PVOH; polyvinyl alcohol.
PVA is a water-soluble synthetic polymer derived from hydrolyzed polyvinyl acetate. The degree of hydrolysis influences solubility, crystallinity, hydrogen bonding, and film-forming behavior. This 99% hydrolyzed grade may require more heat and mixing energy to dissolve than lower-hydrolysis grades because of its higher crystallinity.
Researchers and technical buyers use PVA materials in polymer research, aqueous formulations, film and coating development, adhesives and binders, emulsion stabilization, textile and paper processing studies, and hydrogel-related research. Final suitability should be confirmed under the user’s specific formulation, processing, and end-use conditions.
