-22,000 g/mol PVOH did not form a hydrogel. After three freeze thaw cycles (24 hours @ -20°C, 24 hours at room temperature) the sample was still very much a liquid. This being said, we have concluded this molecular weight is not suitable for our drug delivery system.

Observations

-22,000 g/mol PVOH did not form a hydrogel. After three freeze thaw cycles (24 hours @ -20°C, 24 hours at room temperature) the sample was still very much a liquid. This being said, we have concluded this molecular weight is not suitable for our drug delivery system.
