PVP/VA Copolymer is a white to yellowish-white amorphous powder.
PVP/VA Copolymer is typically spray-dried with a relatively fine particle size.
PVP/VA Copolymer has a slight odor and a faint taste.
PVP/VA Copolymer is a water-soluble polymer used to improve the uptake and drug loading of various pharmaceutical agents, including contraceptive patches.
Pharmaceutical Applications
PVP/VA Copolymer is used as a tablet binder, a film-former, and as part of the matrix material used in controlled-release formulations.
In tableting, copovidone can be used as a binder for direct compression and as a binder in wet granulation.
PVP/VA Copolymer is often added to coating solutions as a film-forming agent.
PVP/VA Copolymer provides good adhesion, elasticity, and hardness, and can be used as a moisture barrier.
Production Methods
PVP/VA Copolymer is manufactured by free-radical polymerization of vinylpyrrolidone and vinyl acetate in a ratio of 6 : 4.
The synthesis is conducted in an organic solvent owing to the insolubility of vinyl acetate in water.
