| 논문초록 | New polyphenylene-based dendronized polymers (denpols), exhibiting extended and rigid conformations, were prepared using ring-opening metathesis polymerization (ROMP). Their mechanochemical degradation was explored in ultrasound-induced elongational flow fields. Degradation rate constants were obtained for denpols of varying generation, across a wide degree of polymerization (DP) range. In general, it was found that larger side chains led to increased degradation rates and that the rate enhancement was proportional to relationships derived from the persistence length or the monomer molecular weight. These relationships led to the generation of "master curves" in which the rate constant trends for each polymer series converged, enabling accurate prediction of degradation rate constants for related polymers bearing large side chains. |
