Anhydrous vs. Hydrated Polymers: Optimizing Polyvinyl Alcohol (PVA) Dissolution Rates in Custom Synthesis
The PVA dissolution problem almost always presents itself in the same way. The researcher added the powder to hot water, stirred for 30 minutes, and obtained a suspension of undissolved gel lumps floating in a thin solution, not the uniform 5% w/v matrix required by the protocol.
