Poli(alcohol vinílico)

Descripción:

Poli(alcohol vinílico) (PVA) es un polímero sintético caracterizado por su solubilidad en agua, biocompatibilidad y propiedades formadoras de película. Se produce a través de la hidrólisis del poli(acetato de vinilo) y es conocido por su excelente adhesión, flexibilidad y resistencia a aceites y grasas. El PVA se utiliza típicamente en diversas aplicaciones, incluidos adhesivos, recubrimientos y películas, debido a su capacidad para formar fuertes enlaces de hidrógeno con las moléculas de agua, lo que mejora su solubilidad. El grado de hidrólisis y el peso molecular pueden influir significativamente en sus propiedades, como la viscosidad y la resistencia mecánica. El PVA también es biodegradable, lo que lo convierte en una opción respetuosa con el medio ambiente en muchas aplicaciones. Además, exhibe buena estabilidad térmica y puede ser modificado para mejorar sus propiedades para usos específicos, como en aplicaciones biomédicas o como componente en materiales compuestos. En general, el PVA es un polímero versátil con una amplia gama de aplicaciones industriales y comerciales.

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.

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.
