Part 1 (Solubility of PVOH)
A)0.5 g PVOH MW:22000 + H20
B)0.5 g PVOH MW:22000 + H20 + H2PO4
C)0.5 g PVOH MW:22000 + H2O + H2PO4 + maleic acid
Solubility of A, B and C were measured by adding each film into separate beaker. Stir bar was placed in to each beaker with A, B and C.
The time required to dissolve each film was recorded.
Part 2 (Cross linking of A, B and C and solubility of each film after crosslinking)
0.5 g of A, B and C were placed into 3 separate teflon plate and placed in to 80 degree celcius oven for 90 minutes.
The time required for each film to dissolve in water was also recorded.
Part 3 (preparing thinner films)
*0.1g of PVOH (MW:22000) + 4ml of water
*0.1g of PVOH (MW:100000) + 4ml of water
This area is for any observations or conclusions that you would like to note.
