Polymer Reaction Engineering in Molecular and Nano Scales

Polymer reaction engineering (PRE) is a discipline to study chemical, physical, and process aspects of polymerization relevant to industrial polymer manufacturing. One of the interesting features of PRE is that it deals with multi-scale problems from molecular-scale to plant scale, which pose unique scientific and engineering challenges. In this presentation, our new and recent research approaches in polymer reaction engineering are illustrated with examples. The first example is the catalytic polymerization of olefins and styrene in silica-coated nanotube reactor (SNTR) arrays developed in our laboratory. The second example is the dispersive suspension polymerization of methyl methacrylate to produce multihollow polymer particles, porous particles, and unusual morphological structures. The detailed kinetic modeling of ethylene-cycloolefin copolymerization process is also illustrated.
