ObjectiveDescriptionPart 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. Solubilities of each film after the cross section 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 Data
