The term "solid" is a broad classification for the physical form of this material. The product may be received as a powder, chunk, or crystals, as these are all considered solid forms. While the appearance and physical form are not assigned specifications for this product, other hydrolyzed polyvinyl alcohol products of similar molecular weights tend to be powder or crystalline powder forms.

Which is the best solvent for PVA to dissolve better. Can this product be used liquid crystal alignment
1 answer-
This product is not tested for solubility. However, the solubility of polyvinyl alcohol (PVOH) is very dependent on the degree of hydrolysis. A higher degree of hydrolysis results in a lower solubility rate. This product is considered fully hydrolyzed and may only be dissolved at relatively low concentrations in hot water, after extended stirring times. It should also be mentioned that ‘fully hydrolyzed’ may range from 99 to 100 %.
This product is not tested for any specific application. Please see the links below to review publications specific to liquid crystal alignment:
