（1）Solubility：The Polyvinyl alcohol powder can be dissolved in water. 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：PVA is almost free from weak acid, weak base, or the impact of organic solvents, oil is very high.
（4）Storage Stability：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 .
