Mechanism of Initiation and Propagation of n-Hexyl Isocyanate by Sodium Benzanilide from DFT Calculations |
초록 |
Recently we found sodium benzanilide (Na-BA) as a very fascinating initiator for the polymerization of n-hexyl isocyanate (HIC) in that it does the dual function of initiation as well as chain end protection. We proposed a structure for the initiator as a self-assembled cluster of five Na-BA molecules to form a weakly interacting pentameric ring. In order to confirm the hypothesis, we investigated the tendency of Na-BA toward cluster formation in the polymerization condition. We used density functional theory (DFT) in combination with the Poisson-Boltzmann continuum-solvation model to calculate the relative populations of (Na-BA)n clusters (n=1-6) in THF at 198 K and compared the DFT energy calculations of the initiator structures with results of the polymerization. |
