PERTANYAAN YANG SERING DIAJUKAN
Q: Is polyvinyl alcohol soluble?
A: Polyvinyl alcohol powder is water soluble with transparent solution. Most PVA series are used while dissolved in water. Its solubility depends mainly on degrees of polymerization and alcoholysis. At the same temperature, the solubility increases along with reduction of the degree of alcoholysis, and decreases with increase of the viscosity; for the PVA series with the same degree of polymerization, if their degrees of alcoholysis are low, their temperatures get low upon completion of dissolution, and vice versa; for the PVA of the same alcoholysis, if the degrees of polymerization are high, their temperatures get high upon completion of dissolution, and vice versa. The PVA at the degrees of alcoholysis above 88 (mol/mol)% depends greatly on temperature changes, that is, dissolution or partial swelling may not take place at a particular temperature.
