| Abstract: | The transmittance of poly(vinyl alcohol)(PVA) aqueous solution and salt solution were characterized by UV-vis spectrophotometer. The effects of alcoholysis degree of PVA,electrolyte and temperature on the transmittance of PVA solution were investigated. The experimental results showed that UV-Vis method was a simple and feasible method to determine the transmittance of PVA solution. |
