In this paper, the dynamic mechanical properties of the natural rubber (NR) which was filled with in situ zinc dimethacrylate (ZDMA) were investigated using a Rubber Process Analyzer (RPA2000). A weak rigid filler–filler network was formed in the uncured NR/ZDMA compounds. Pronounced Payne effect and stress‐softening behavior were observed in the vulcanizates, which indicated that a strong and special filler structure was formed after vulcanization. However, an ionic network might be formed with a high ZDMA loading, which was not favorable to rebuild the poly‐ZDMA network. Finally, two tentative regions of networks deformation during the dynamic strain sweep were discussed: filler–filler and ionic bonds dominating region and rubber network dominating region. POLYM.
