Polyvinyl Alcohol is made from vinyl acetate produced by means of calcium carbide route, with methanol as solvent and azo-diisobutyronitrile the initiator, by polymerization, alcoholysis, disintegration, separation and desiccation.

Features

• Polyvinyl Alcohol is a kind of non-ionic linear high polymer. It is non-toxic, non-smelly, and in white or light yellow, in the form of floccules, flake and solid powder.

• Polyvinyl Alcohol has fairly good chemical stability, insulativity and film-forming properties. It has typical chemical properties of polyalcohol.

• Polyvinyl Alcohol soluble in water, its water solution has good property of adhesion, filming, it can be resistant to most of organic solvents, such as oils, lubricants and hydrocarbons, has chemical property of long chain polyalcohol esterification, etherification and acetalation.

• It can react with acid, ether and acetyl, and it can be esterified, etherified and actualized. In addition, it has unique characteristics of its own.
