Polymer networks in rubber vulcanizates are commonly characterized by cross-link density and cross-link structure. These cross-link characteristics greatly influence the properties of vulcanized rubber compounds. Therefore, their reliable characterization is essential. This study explores if Temperature Scanning Stress Relaxation (TSSR) can be used as a safer, more cost-effective and time-saving method to quantify polymer network density and to distinguish different types of sulfidic cross-links in filled rubber compounds.
