Abstract
Blends containing poly(vinylpyrrolidone) (PVP) of three different molecular weights and poly(monoitaconates) (PMI) with different side chain structures were prepared. Polymer blends of various compositions were analyzed by Differential Scanning Calorimetry (D.S.C.). The calorimetric study was performed on films prepared from methanol and dimethylformamide (DMF). One Tg value is observed for the majority of the samples over a wide range of composition, but in all cases a minimum in the Tg-composition diagram is observed which is attributed to an interpolymer complex formation. The analysis of these systems in solution by using turbidimetry and viscometry techniques for PMMI/PVP confirms the results obtained in the solid state.
