Abstract
The miscibility of poly(styrene) and poly(vinylmethylether) is studied both by measuring the glass transition temperatures of the mixture and with the application of the Flory-Prigogine theory in the approximated form due to Patterson. For these calculations, the enthalpy of mixing of the two polyme rs is evaluated by measuring the enthalpies of solution of the pure polymer s and of the mixture. The trend of the interaction parameters with the temp erature for two samples of poly(styrene) of different molecular weight is d iscussed. (C) 2001 Elsevier Science B.V. All rights reserved.
