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.
