Polypropylene (PP) impact copolymer is one of the heterophasic PP systems that is improved by rubber modification. Because the copolymer is a complicated polymer blend; which mainly consists of PP and ethylene-propylene rubber (EPR) components; the degradation behavior has hardly been studied. In this study; the thermal degradation of the copolymer was studied through direct observation by atomic force microscopy; which is a powerful tool for observing a local domain in a polymer blend. The deg radation behavior was visually captured by the mapping of topological changes. Although the EPR phase was hardly degraded; the neighboring PP matrix was degraded selectively. The degradation behavior of the copolymer was found to be heterogeneous. © 2006 Wiley Periodicals; Inc;
