Abstract
In this study, it is demonstrated that large particles with sizes at least two orders of magnitude greater than that of the rubber latex component, are similar in composition to the host ABS but have enhanced ABS-g1 content. Poor bonding between the large particle and surrounding material causes stress concentration under loading, thus leading to fracture of the specimens. The batch-dependence of the toughness for the blended ABS is attributed to variation in the quantity and distribution of the large particles.
