Abstract
The miscibility behavior and the specific interactions of binary blends of poly(ethylene oxide) (PEO) and poly(vinyl methyl ether) (PVME) with poly(p-vinylphenol) (PVPh) are investigated by DSC, analogue calorimetry, and FTIR spectroscopy. The Kovacs free volume theory is able to reproduce the glass transition behavior of both systems quite well, although excess volume measurements of PVME/PVPh blends do not support the physical meaning assigned to the parameters in the theory. The specific nature and the average strength of the intermolecular interaction for the polymer blends and the analogue mixtures are determined by FTIR measurements
