Phase morphology map in LCST-type polymer blends with dynamical asymmetry under different quench depths
Abstract
With increasing temperature, a transition from fracture phase separation (FPS) to viscoelastic phase separation (VPS) was found in dynamically asymmetric PS/PVME blends with LCST behavior. Typical morphology formed via VPS disappeared under large quench depths, indicating some other specification might control the morphological evolution during VPS besides the dynamic asymmetry.
