In this work, we use Mesoscopic Dynamic (MesoDyn) density function simulation to study the compatibility of polymer blends. The mesoscale model for Poly (methyl methacrylate) (PMMA) and Poly (ethylene oxide) (PEO) were set up. The free energy, enthalpy, entropy, order parameters and density profiles were got by the simulation. The results showed that the free energy density keeps constant negative value and the order parameters is much less than 0.1. And phase separation behavior was not observed during the whole simulation time. Using density profiles, the kinetics of phase separation was examined and the phase separation behavior. These indicates that PMMA and PEO is miscible.
