Abstract

The structural development of polystyrene, which was crosslinked with varying amounts of the multifunctional cluster Zr6O4(OH)4(methacrylate)12, was followed in situ by small-angle X-ray scattering at a synchrotron radiation source. It was observed that crazing strongly diminishes with increasing cluster proportion and disappears nearly completely for the material with the highest cluster proportion of 0.87 mol-%. Accordingly, the maximum stress before failure is strongly enhanced, whereas the maximum strain decreases.
