  • Raw material polyvinylpyrrolidone pvp

    Polyvinylpyrrolidone (PVP) is a polymer that is synthesized from the monomer vinylpyrrolidone. The production of PVP involves the polymerization of vinylpyrrolidone monomers through various methods, such as solution polymerization or precipitation polymerization. The raw material for PVP production is therefore vinylpyrrolidone. Vinylpyrrolidone (VP) is typically derived from the reaction between 2-pyrrolidone and acetylene or by the reaction of 2-pyrrolidone with vinyl acetate followed by hydrolysis. The resulting vinylpyrrolidone monomer is then used as the building block for PVP production. The quality and properties of PVP can be influenced by the choice of raw materials, the polymerization process, and the purification steps. Different grades of PVP may be available based on factors such as molecular weight, purity, and specific applications. It’s worth noting that PVP can also be copolymerized with other monomers, such as vinyl acetate, vinyl alcohol, or acrylic acid, to introduce additional properties or functionalities to the polymer. These…

  • Molecular weight of polyvinylpyrrolidone

    Polyvinylpyrrolidone (PVP) is a fine chemical downstream of acetylene.
