Polyvinyl alcohol: water-soluble, biodegradable polymer; used for biomedical applications and medical excipients.

Polyvinyl alcohol is a polymer that is synthesized by the polycondensation of vinyl acetate and hydrochloric acid. Polyvinyl alcohol has been shown to be effective in treating bowel diseases, such as inflammatory bowel disease, due to its ability to bind to sodium citrate and methyl ethyl. Polyvinyl alcohol also has intramolecular hydrogen bonding, which allows for the formation of hydrogen bonds between polyvinyl alcohol molecules. The intermolecular hydrogen bonding of polyvinyl alcohol is stronger than the intramolecular type because it involves two separate molecules. Polyvinyl alcohol can be used as a thickener or stabilizer in foods, such as ice cream, salad dressing, and sauces. It can also be used in pharmaceuticals as a coating for tablets or capsules. As an antimicrobial agent, polyvinyl alcohol has been shown to have inhibitory effects on enzymes that are involved with bacterial growth (e.g., aminopeptidase).

Polyvinyl alcohol is used as a biological reagent to test the dispersion of zinc oxide nanoparticles. It is an effective protein resistant material and is used to stabilize gold colloids of diameter 3-8nm. It is used as an emulsion polymerization aid to make polyvinyl acetate, as a protective colloid, as a film used in the water transfer printing process, as a surfactant for the formation of polymer encapsulated nanobeads, as an embolization agent in medical procedures and as a fixative for specimen collection.

Polyvinyl alcohol is used in food industries as a binding and coating agent. Its viscosity favors the application as coating agent to tablets and capsules. Mixed-matrix membrane prepared by dispersion of NaA zeolite particles is used to study the pervaporative separation of water-butanol mixtures. Polyvinyl alcohol /gelatin based biocompatible polymeric scaffolds have been developed for 3D cancer models.

Polyvinyl alcohol is a polymer that is used as a coating material, adhesive, and in the manufacture of certain plastics. It has been shown to have anti-inflammatory properties and may be effective for bowel disease. Polyvinyl alcohol can be prepared by hydrolysis of polyvinyl acetate using sodium carbonate or zirconium oxide as catalysts. The enzyme activities of polyvinyl alcohol are dependent on the molecular weight, which is usually between 67,000 and 1 million. Polyvinyl alcohol can be manufactured by esterification of vinyl acetate with anhydrous ethanol followed by hydrolysis with sodium hydroxide. It has also been shown to inhibit bacterial growth by forming hydrogen bonds with the bacterial cell wall.
