Description

Hydrogels (synthesized on http://openwetware.org/wiki/User:Samiye_Yaman/Notebook/Lab_581/2013/02/06) were sink at the bottom of the beaker. By using sonicator, the hydrogel were separated. Rest of solution was separated into layers by using separatory funnel. Water was used.

Data

Hydrogels placed in to various pH of HCl (http://openwetware.org/wiki/User:Samiye_Yaman/Notebook/Lab_581/2013/02/08) did not dissolve in any of the pHs.

Results from Swelling studies (http://openwetware.org/wiki/User:Samiye_Yaman/Notebook/Lab_581/2013/02/08)

1)Final mass of PVOH (MW: 146,000)=0.4526g

2)Final mass of PVOH (MW: 130,000)=0.8244g

3)Final mass of PVOH (MW: 89,000-98,000)=0.7608g
