:Poly(alcool vinylique)
Description :
Poly(alcool vinylique) (PVA) est un polymère synthétique caractérisé par sa solubilité dans l'eau, sa biocompatibilité et ses propriétés de formation de film. Il est produit par hydrolyse du poly(acétate de vinyle) et est connu pour sa excellente adhérence, sa flexibilité et sa résistance aux huiles et aux graisses. Le PVA est généralement utilisé dans diverses applications, y compris les adhésifs, les revêtements et les films, en raison de sa capacité à former de forts liaisons hydrogène avec les molécules d'eau, ce qui améliore sa solubilité. Le degré d'hydrolyse et le poids moléculaire peuvent influencer de manière significative ses propriétés, telles que la viscosité et la résistance mécanique. Le PVA est également biodégradable, ce qui en fait une option respectueuse de l'environnement dans de nombreuses applications. De plus, il présente une bonne stabilité thermique et peut être modifié pour améliorer ses propriétés pour des usages spécifiques, comme dans les applications biomédicales ou comme composant dans des matériaux composites. Dans l'ensemble, le PVA est un polymère polyvalent avec une large gamme d'applications industrielles et commerciales.

CAS :<p>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.</p>Formule :(C2H4O)xDegré de pureté :Min. 95%Couleur et forme :PowderPoly(vinyl alcohol), average Mw 150,000 - 200,000

CAS :<p>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.</p>Formule :C2H4OnDegré de pureté :(Hydrolysis) 98.0 To 99.9 Mol-%Couleur et forme :PowderPolyvinyl alcohol,Mw 9000-10000
