Effects of polyvinylpyrrolidone both as a binder and pore
TīmeklisGeneral description. Polyvinylpyrrolidone (polyvidone, povidone, or PVP) is a synthetic water-soluble polymer consisting of linear 1-vinyl-2-pyrrolidinone groups. It is hygroscopic and readily absorbs up to 40% of water by its weight. It has excellent wetting properties in solution and easily forms films, which makes it suitable for use … Tīmeklisβ-Mercaptoethanol. 0.02 mL. 0.2%. H 2 O. 2.48 mL. 24.8%.
