Polyvinyl alcohol is a synthetic, water-soluble polymer made through the hydrolysis of polyvinyl acetate, widely used in textiles, adhesives, paper coatings, and medical formulations.
Polyvinyl alcohol properties include film-forming ability, chemical resistance, biocompatibility, and adhesiveness. It is also non-toxic, biodegradable, and exhibits excellent tensile strength and flexibility when used in films.
The melting point of polyvinyl alcohol is not sharply defined, as it decomposes around 200–230°C rather than melting cleanly, due to its polymeric structure and hydrogen bonding.
Polyvinyl alcohol solubility in water depends on its degree of hydrolysis and molecular weight, but it is generally highly soluble in hot water and forms clear, viscous solutions.
Polyvinyl alcohol is used in pharmaceutical coatings, eye drops, packaging films, textile sizing, and 3D printing, thanks to its biocompatibility and water solubility.
