Acetic acid ethenyl ester, polymer with 1-ethenyl-2-pyrrolidone 1-Vinyl-2-pyrrolidone polymer with vinyl acetate
Copovidone is a copolymer of 1-vinyl-2-pyrrolidone and vinyl acetate. It is a white to yellowish-white amorphous powder. Copovidone is typically spray-dried with a relatively fine particle size. It is used as a tablet binder. In tableting, copovidone can be used as a binder for direct compression and wet granulation.
