제목 | Computer Simulational Study on the Addition Effect of 1,2-DACH in the Polymerization System of AN |
초록 | The possibility of stereocontrol of PAN with the addition of 1,2-diaminocyclohexane (DACH) in the polymerization system of acrylonitrile (AN) was investigated by the molecular dynamics (MD) and the density functional theory (DFT). In the MD simulations based on the NVT ensemble, it was observed that the complex structures of two acrylonitrile with 1,2-DACH were different with the cis- and trans-configurations of 1,2-DACH. In the DFT, structures and energies of reactants, transition states, and products were analyzed using Dmol3, respectively. And it was elucidated that how two different configurations of 1,2-DACH influenced on tacticities of PAN, such as syndio- or iso-product. |
