Degree of Hydrolysis: 98% hydrolyzed, indicating a high conversion rate from polyvinyl acetate to polyvinyl alcohol, which enhances the polymer's crystallinity and water resistance.

Molecular Weight: High molecular weight, typically ranging from approximately 31,000 to 50,000 g/mol, contributing to the polymer's viscosity and film-forming capabilities.

Physical Form: Generally available as a white to off-white granular powder, facilitating ease of handling and dissolution.

Solubility: Soluble in water; higher degrees of hydrolysis require elevated temperatures for dissolution. For 98% hydrolyzed PVA, heating to around 96°C is necessary to achieve complete solubility.

Viscosity: A 4% aqueous solution at 20°C typically exhibits a viscosity of approximately 6 centipoise (cP), indicating moderate thickness suitable for various applications.

Melting Point: Exceeds 220°C, reflecting the polymer's thermal stability.

Density: Approximately 1.29 g/cm³, consistent with other high-molecular-weight polymers.
