  • Mechanochemically‐Assisted Synthesis of Polyimides ...

    Herein, we develop a protocol for the synthesis of polyimides in high yields and short reaction times of usually less than 1 h (Figure 1 ). As a model reaction the polymerization between pyromellitic dianhydride (PMDA) and 1,3,5-tri (4-aminophenyl)benzene (TAB) was chosen. Furthermore, we expanded the concept to different polymer architectures.
