For preparing PVA thin films I've tried dissolving PVA in various solvents in all suitable temperature conditions. Even stirring overnight, it still has not dissolved. Kindly suggest the possible solvent or conditions for dissolving 186,000 Mw PVA.

you need to incubate PVA in water at 90C a few h and I am sure it wil be dissolved. What is the degree of deacetilation?

Hi,
If you can have a higher agitation and more temperature, you can dissolve it in the best solvent, water.
