Solution- and Solid-state Mechanochemistry of Polymers from Varying Macromonomers |
| 초록 |
We screened degradation profiles of diverse polymers with the same backbone structure to investigate the influence of the polymer side chains on the polymer’s mechanochemical reactivity in different environments. A broad scope of linear, bottlebrush, and dendronized polymers with varying structures and sizes of side chains were synthesized by Ring-Opening Metathesis Polymerization (ROMP). A systematic study on their degradation kinetics in solution-state (ultrasonication) and solid-state (ball-mill grinding) revealed the critical parameters that could influence polymers’ chain scission events. Furthermore, we utilized these polymers as a multi-mechanophore polymers skeleton, and we figured out the key factors which determine the side chain scission event and mechanophore activation efficiency. These results are expected to be an essential foundation for tuning the efficiency of novel mechano-responsive polymer systems. |
