Abstract
In this work, we have studied the deformation behavior of sulfonated polystyrene ionomer/polystyrene (PS) blends in order to understand the effect of a hard, ionomer-rich second phase on mechanical properties, especially on toughness of the glassy polymers. The micromorphology and deformation mechanisms of ionomer/PS blends were studied by transmission electron microscopy (TEM). Blend samples studied all show a phase-separated microstructure, and phase inversion occurs as the ionomer content increases. It is observed for ionomer/PS (10/90 and 30/70) blends that the rigid ionomer-rich, second phase particles generate many small crazes and that they also elongate substantially along the stress direction.
