ObjectiveTo create crosslinked films through acid catalyzed dehydration and to perform viscosity tests.
DescriptionFilm Preparation with Acid Dehydration
Film 1 - 0.5110 g PVA in 3 mL water, no acid was added Film 2 - 0.5053 g PVA in 3 mL water, 2 drops of phosphoric acid was added Film 3 - 0.5078 g PVA in 3 mL water, 2 drops of 12 M hydrochloric acid was added Film 4 - 1.0084 g PVA in 6 mL water, no acid was added Film 5 - 1.0010 g PVA in 6 mL water, 3 drops of phosphoric acid was added Film 6 - 1.0044 g PVA in 6 mL water, 3 drops of 12 M hydrochloric acid was added
The viscosity of the MW = 130,000 PVA and the MW = 22,000 PVA were measured.
