# 0.5 g and 1.0 g of PVA (MW = 130,000) were measured out. | |||
# The 0.5 g aliquot was dissolved in 3 mL, while the 1 g sample was dissolved in 6 mL of water. | |||
# The samples were heated and stirred to about 70°C to help the PVA dissolve. | |||
# Because the PVA was not dissolving well, 2 mL of water was added to each sample. | |||
# The gels were allowed to evaporate through Friday. | |||
