| Résumé : |
Chemically converting monomer via oxidizing and reducing agents (redox) in post-polymerization is a widely used technique ; however, little time or effort is typically invested in optimizing this step. Through redox optimization, cost savings can be realized via shortened cycle times while also reducing residual free monomer to non-detectable levels.
While temperature and pH play a major role in the kinetics of redox chemistry, these are variables that often cannot be altered. However, improvements can be achieved regardless of these conditions as well as process or equipment restraints. A few of the variables that impact reaction time in the postpolymerization step that can more easily be optimized include redox pair, dosage/concentration, rate, and method of addition. A series of tests were performed to study the impact of these factors. |
