Abstract The structural development of polystyrene, which was crosslinked with varying amounts of the multifunctional cluster Zr 6 O 4 (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.
