Aiming at "polymer preparation process engineering", our group carries out the design, optimization and scaleup of reactor, process simulation and optimization of the polymerization process, the polymer reactive extrusion and modification. Combining the computational chemical engineering and experimental study, we reveal the non-ideal characteristics of the polymerization reactor to achieve the optimal design of the reactor; closely integrated industrial polymerization reactor based on the mechanism and kinetics of polymerization, to modeling, optimizating, soft measurement and control of the polymerization process; study the principle of polymer reactive extrusion process and morphology evolution based on reaction engineering theory, to realize the high performance modification of polymer material.
