Özet

The miscibility of dextran, Dx, and poly(ethylene glycol), PEG, have been studied in solid state by FTIR, Raman, DSC and XRD methods. In order to investigate the effect of solvent on the miscibility of Dx and PEG, their homopolymers and blends having different compositions were cast from aqueous and DMSO solutions. Following the above mentioned experimental methods, it has been seen that specific interactions causing partial miscibility exist between Dx and PEG and these interactions occur to a higher extent by choosing DMSO as the solvent, that is, the choice of solvent has a great influence on the miscibility behavior of the polymer blends.
