    Phase separation, phase dissolution and crystallization in poly(e-caprolactone)/poly(styrene-co-acrylonitrile) blends

  • Original language description

    A blend of poly(e-caprolactone) (PCL) and poly(styrene-co-acrylonitrile) (SAN) containing 27.5 wt% of acrylonitrile having the critical composition (80/20 PCL/SAN) was studied. This PCL/SAN blend having a lower critical solution temperature (LCST) phaseboundary at 122°C offered an excellent opportunity to investigate, firstly the kinetics of phase separation above LCST (125-180°C), and secondly the kinetics of phase dissolution below LCST (50-115°C). The blend underwent a temperature-jump above LCST where spinodal decomposition (SD) proceeded, yielding a regularly phaseseparated structure (SD structure). Then, it was quenched to the temperatures below LCST when the phase dissolution proceeded. Optical microscopy was used to observe the spinodal decomposition qualitatively while light scattering was used to characterize the phase separation and phase dissolution quantitatively. It was found that during phase dissolution the peak maximum moved towards a smaller angle (wavelength of conc
