Abstract:

The lack of fundamental data on the properties of polyvinyl alcohol prompted an investigation of the available thermodynamic parameters of this material. From published data the entropy, enthalpy and Gibbs free energy were calculated over the temperature range 10 to 245 K. The thermodynamic function CpT was calculated and exhibits a maximum at about 80 K which is attributed to interactions between chains. The model of Stockmayer and Hecht was used to study the thermal motions of polyvinyl alcohol at low temperatures. Author
