Abstract

The miscibility behavior of the blends of polysulfone (PSf) and polydimethylsiloxane (PDMS) was studied in dilute 1,2- dichloroethane solutions at 25 0C. The intrinsic viscosity and Huggins’ parameter of the binary mixtures were determined from the intercept and slope of the linear straight line between specific viscosity and the overall polymer concentration at the studied compositions. From experimental results of the intrinsic viscosities of the mixtures, some miscibility parameters b , b , b , Δ[η] and β were obtained by applying the criteria proposed by the research groups Krigbaum and Wall, Catsiff and Hewett, Garcia et al. and Jiang and Han, respectively. The miscibility of mixtures was also studied by using differential scanning calorimetry and fourier transform infrared spectroscopy..
