1. Full name and chemical composition of VP/VA copolymer
● Chemical name and monomer composition
The full name of VP/VA copolymer is Vinyl Pyrrolidone/Vinyl Acetate Copolymer, which is synthesized by free radical polymerization of two monomers:
1. Vinyl Pyrrolidone (VP): provides water solubility and biocompatibility.
2. Vinyl Acetate (VA): enhances film-forming properties and hydrophobicity.
3. The ratio of the two monomers is usually 70:30 to 30:70, and different ratios give the product differentiated properties, such as solubility, mechanical strength and stability.
●Molecular structure and characteristics
VP and VA units are alternately arranged in the molecular chain of VP/VA copolymer to form a block or random copolymer structure. Its characteristics include:
1. Film-forming property: After drying, it forms a transparent and flexible film, which is widely used in drug coating and cosmetic shaping.
2. Adhesiveness: As a tablet binder, it improves the hardness and anti-fragility of the preparation.
3. Environmental adaptability: By adjusting the VA ratio, the product's sensitivity to humidity can be controlled to avoid moisture absorption and deterioration of the preparation.
2. Current status and growth potential of global and Chinese markets

Product Features
⑴Povidone: It is a linear 1-vinyl-2-pyrrolidone synthetic polymer that can absorb toxins. It is usually made into injections and used for certain poisoning diseases.
⑵ Cross-linked povidone: It is a water-insoluble synthetic cross-linked N-vinyl-2-pyrrolidone homopolymer. It is a white or off-white powder, almost odorless, and hygroscopic. It is insoluble in water, ethanol, chloroform or ether. It has a high capillary/water content, a large specific surface area, extremely strong hydration ability, high and rapid water absorption, strong water absorption and expansion ability, and a swelling coefficient of 2.25-2.30. It also has the same complexing ability as polyvinyl pyrrolidone and can complex a variety of substances. It is often used as a water-insoluble tablet disintegrant, dry adhesive, filler and excipient, etc. It can also be used as a dissolution promoter.
