Poly(vinyl alcohol)

Description:

Poly(vinyl alcohol) (PVA) is a synthetic polymer characterized by its water-solubility, biocompatibility, and film-forming properties. It is produced through the hydrolysis of poly(vinyl acetate) and is known for its excellent adhesion, flexibility, and resistance to oils and greases. PVA is typically used in various applications, including adhesives, coatings, and films, due to its ability to form strong hydrogen bonds with water molecules, which enhances its solubility. The degree of hydrolysis and molecular weight can significantly influence its properties, such as viscosity and mechanical strength. PVA is also biodegradable, making it an environmentally friendly option in many applications. Additionally, it exhibits good thermal stability and can be modified to enhance its properties for specific uses, such as in biomedical applications or as a component in composite materials. Overall, PVA is a versatile polymer with a wide range of industrial and commercial applications.

Polyvinyl alcohol,Mw~67,000

CAS: 9002-89-5

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.

Polyvinyl alcohol - Mw 67,300 - 90,000

CAS: 9002-89-5

Polyvinyl alcohol is a water-soluble polymer that can be synthesized by the hydrolysis of polyvinyl acetate. It has been used as a model system to study the reaction mechanism and enzymatic activity of polyvinyl alcohol. The hydrolysis of polyvinyl acetate yields vinyl acetate, which then reacts with water to form polyvinyl alcohol. Polyvinyl alcohol can be synthesized by the addition of benzalkonium chloride or x-ray diffraction data. Polyvinyl alcohol is also present in many autoimmune diseases, such as lupus erythematosus. It is often used for wound dressings due to its ability to absorb fluids and promote healing. Polyvinyl alcohols are also used in laser ablation because they do not burn easily and are low cost.
