Abstract:PA6 and POE were simulated by molecular dynamics (MD) and mesoscopic dynamics (MesoDyn) for predicting properties of PA6/POE blends such as the compatibility, the glass transition temperature (Tg), mechanical properties and binding energy of PA6/POE blends. Results show that the Tg has been determined by the slope of the V-T simulation data, and the Tg of PA6/POE are respectively corresponding to Tg of PA6 and POE, which are incompatible system. MesoDyn simulation method was used to simulate the mesoscopic phase separation behavior of PA6/POE. The order parameters computed for the blends can predict that the blends are incompatible systems. Therefore, the method used in this work is a useful tool to provide properties of a given polymer blends. In addition, it is a promising technique to help screen polymer formulations before experimental tests.
