This article presents novel biobased ionomers featuring self‐healing abilities. These smart materials are synthesized from itaconic acid derivates. Large quantities of itaconic acid can be produced from diverse biomass like corn, rice, and others. This study presents a comprehensive investigation of their thermal and mechanical properties via differential scanning calorimetry (DSC), thermo gravimetric analysis (TGA), and FT‐Raman and FT‐IR measurements as well as dynamic mechanic analysis. Within all these measurements, different kinds of structure‐property relationships could be derived from these measurements. For example, the proportion of ionic groups enormously influences the self‐healing efficiency. The investigation of the self‐healing abilities reveals healing efficiencies up to 99% in 2 h at 90 °C for the itaconic acid based ionomer with the lowest ionic content.
