Product Description:

Poly(methyl vinyl ether-alt-maleic anhydride) is a synthetic alternating copolymer composed of methyl vinyl ether and maleic anhydride monomers. Its structure features a reactive anhydride ring along the polymer backbone, which can be hydrolyzed to form carboxylic acid groups, imparting pH-responsive and adhesive properties. This polymer is widely used as an industrial auxiliary agent, particularly as a thickener, stabilizer, and film-forming agent in adhesives, coatings, and personal care products. In the pharmaceutical field, it serves as a pharmaceutical excipient, functioning as a binder and film coating material for tablet formulations due to its excellent mucoadhesive and controlled-release properties. Its reactivity also allows for crosslinking or derivatization to tailor functionality for specific applications.
