Respected Sir,

Following steps would be helpful to prepare PVA solution:

PVA is soluble in hot and cold water.

1. The powder is slowly added to the cold water to avoid formation of lumps, as it becomes sticky and the tendency to form lumps increases as temperature rises. In some cases water at lower than ambient temperature may be used to reduce this risk.

2. Once the powder is fully dispersed the mix is heated to the temperature at which the polymer becomes solubilized (ranging from 194ºF to 208ºF - this depends on the grade of PVA used).

3. Mixing continues at this temperature until the PVA is fully solubilized. Depending on the grade of material and efficiency of the agitation system this can take some time to achieve.

Hope this information is useful.
