Description

  • masses of the hydrogels after the swelling study were measured.
  • Rest of solution was separated into layers by using separatory funnel. Water was used.

Data

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
