Poly(vinyl alcohol) is a highly crystalline polyhydroxy polymer produced by the hydrolysis of poly(vinyl acetate), as the vinyl alcohol monomer is not available. The polymer is water‐soluble, possesses excellent tensile strength, abrasion resistance, superior oxygen barrier properties, as well as excellent emulsification and protective colloid properties, and exhibits solvent, oil, and grease resistance that are matched by few other polymers. Poly(vinyl alcohol) undergoes chemical reactions in a manner similar to other secondary polyhydroxy alcohols. Fully biodegradable, the polymer is considered a nonhazardous material according to the American Standard for Precautionary Labeling of Hazardous Industrial Chemicals. Industrial applications are all based on and limited by the use of water solutions. The polymer is not considered thermoplastic because the degradation temperature is below the melting point. Poly(vinyl alcohol) is commercially available in granular and powdered form. Grades include both fully hydrolyzed and partially hydrolyzed products. A wide variety of molecular weight and hydrolysis is commercially available. Principal end uses include textile sizing, adhesives, protective colloid for emulsion polymerization, paper coating, cement and mortar additive, poly(vinyl butyral), fibers, and films.
