Tuning the Composition of Graft Polymers to Modulate Mechanochemical Degradability |
| 초록 |
We have studied the degradation of graft polymers in solution with ultrasonication. By synthesizing a library of graft copolymers with varying composition, we could determine the influence of specific parameters on the degradation behavior. These compositional modifications include changing the polymer backbone length, grafting density, arm architecture (e.g., linear vs dendritic), arm size (e.g., length or generation), and arm chemical composition. These parameters can influence both the kinetics of chain scission and the location of chain scission events within the polymers. These studies have enabled the identification of the persistence length as a key kinetic parameter for the ultrasonic degradation of graft polymers. |
