Abstract
Blends of poly(vinyl methyl ketone) (PVMK) with poly(2-hydroxyethyl methacrylate) (PHEMA) and poly(epichlorohydrin) (PECH) were prepared by casting from a common solvent. It was found that all the PVMK blends are miscible and show a single, composition-dependent glass transition temperature ( T g). The T g composition dependence has been analysed by the use of the Gordon-Taylor equation. A FTIR study revealed that a hydrogen-bonding interaction occurs between the components of the PVMK/PHEMA blends and it is slightly stronger than in pure PHEMA. The observed miscibility of PVMK with PHEMA, as well as with PECH, can be considered to be due to hydrogen-bonding interactions between the components.
