Phase Separation Induced by Shear Quenching in Polymer Blends with a Diblock Copolymer

Abstract

The effects of adding A–B diblock copolymer to a polymer blend (A/B) on phase-separation kinetics and morphology have been investigated in a fixed shallowquench condition (DT 5 1.5 °C) by in situ time-resolved light scattering and phasecontrast optical microscopy. A shear-quench technique was used in this study instead of a conventional temperature-quench… (More)
