常见问题
Q: 聚乙烯醇的属性指数是多少？
A: Polyvinyl alcohol PVA is a solid substance, colorless and scentless in the shape of floccus, flake or granule. As it contains plenty of hydroxyl groups in its molecule, PVA is easily soluble in water as well as in organic compounds also containing hydroxyl such as glycerol, glycol, acetic acid, acetaldehyde and benzoic acid, except for general organic solvents in which it is insoluble. When heated up to 130-140℃, PVA gets yellow without essential changes in nature; when at 160℃ for a longer time, it gets darker; at 200℃, inter-molecular dehydration takes place with lower water solubility; at above 200℃, intra-molecular dehydration takes place; nearly at 300℃, PVA is decomposed into water, acetic acid, acetaldehyde and crotonaldehyde. The bulk densities of PVA vary depending on methods of alcoholysis: 0.2~0.27g/ml for high alkali alcoholysis and 0.42~0.52 g/ml for low alkali alcoholysis.
