Anhui Wanwei High Tech Materials Co., Ltd. is the core subsidiary of Anhui Wanwei Group Co., Ltd., has five R & D institutions such as national enterprise technology center, post doctoral workstation and skill master studio, was listed on the Shanghai Stock Exchange in May 1997 (the stock name is wanwei high tech and the code is "600063").
Anhui Wanwei Group Co., Ltd. is a large enterprise under the jurisdiction of Anhui state owned assets supervision and Administration Commission. The company's main business is the R & D, production and sales of polyvinyl alcohol (PVA) and its derivatives. The production and sales of PVA and high strength and high modulus PVA fiber have ranked first in the same industry in China for many years; PVB resin and film are at the forefront in China, and PVA optical film is the first in China.
（ CH3CHCOOCH3 ）x （ CH2CHOH ）y
in which: x + y indicates the degree of polymerization, y / (x + y) that alcoholysis degree
(1)Solubility：
Polyvinyl alcohol (PVA) molecules are easily soluble in water due to their abundant hydroxyl groups. Its solubility increases with the increase of water temperature, only expanding in cold water (low alcoholysis products can slowly dissolve in room temperature water), and fully dissolving in hot water. Its aqueous solution has good film-forming and bonding properties.
PVA with Less than 95%alcoholysis degree can be dissolved in water at room temperature and PVA with more than 99.5% alcoholysis degree can only be dissolved in hot water above 95℃.
(2)Thermal Stability：
The heat can make PVA soften and there is no significant change below 40℃ but 160 ℃ or more, for a long time heated ,it will gradually be colored .when 220℃ above it is decomposed to produce water, acetic acid, acetaldehyde and propylene aldehyde.
(3)Chemical Resistance：
Polyvinyl alcohol (PVA) is almost free from weak acid, weak base, or the impact of organic solvents, oil is very high.
(4)Storage Stability：
Polyvinyl alcohol (PVA) is a low viscosity of the polymer, the solution is stable at room temperature. Aqueous solution in the storage process is not degenerate.
(5)Film：
As the high adhesion between PVA molecular, PVA is easy to form a colorless, transparent film with good mechanical strength, smooth surface without tacky, and good solvent resistance. Monolayer has excellent light-admitting quality , high permeability rate, no charged, no absorption and good printing character .
(6)The Chemical Property:
Polyvinyl alcohol (PVA) can be seen as a linear polymer with a hydroxyl polymer. Hydroxyl of molecules which has high activity can be a typical chemical reaction of low-alcohol, such as esterification, etherification, acetal, etc and can also react with a number of inorganic compounds or organic compounds.
The appearance is white flake, granular, or powdery solid (low alkali alcoholysis process) or white flocculent solid (high alkali alcoholysis process). Specific gravity: 1.23-1.31g/cm3, filling specific gravity of sheet PVA: 0.42-0.52g/cm3, filling specific gravity of flocculent PVA: 0.20-0.27g/cm3.

Polyvinyl alcohol (PVA) can be used as an adhesive for many different materials, such as paper, textiles, wood, plastics, etc. It has high viscosity and good durability, making it widely used in industrial applications such as paper and fiberboard manufacturing.
Polyvinyl alcohol (PVA) can also be used to manufacture various coatings and adhesives, such as wall coatings, wood coatings, adhesives, etc. In these applications, PVA can provide good adhesion and water resistance.
Due to its excellent water resistance and high transparency, PVA is also used as a packaging material, such as food packaging bags and cosmetics packaging.
Polyvinyl alcohol (PVA) can also be used to manufacture medical supplies, such as eye drops, artificial blood vessels, wound dressings, etc. These products, due to their excellent biocompatibility and biodegradability, can effectively help treat diseases and wounds.
Polyvinyl alcohol (PVA) can also be used for cellulose fiber processing, such as manufacturing cellulose pads and artificial plush toys.
