Analysis of mass transport limitation during emulsion - Polymerization using reaction - Calorimetry and conductivity measurement

摘要

The seeded emulsion Polymerization of styrene was investigated by reaction calorimetry in combination with conductivity measurements using the RC1e calorimeter (Mettler Toledo). Varying the stirrer speed showed the existence of mass transport limitation in the lower speed range. For the case of using the autoclave HP60 with an anchor stirrer a minimum stirrer speed of 400 rpm is required to be sure of adequate mixing in the reactor. [References: 8]
