Synthesis and characterization of a novel dimethacrylate based on adamantane as possible dental resins

► A novel dimethacrylate based on adamantine (AB-GMA) was synthesized. ► AB-GMA exhibited high degree of double bond conversion (up to 77%). ► AB-GMA had good thermo-mechanical properties. ► AB-GMA showed no cytotoxicity and had good in vitro biocompatibility.
