SENSORS: Reaction Monitoring of Glycerol Step-Growth Polymerization Using ATR-FTIR Spectroscopy
Somaieh Salehpour, Marc A. Dubé*
Step-growth polymerization of glycerol is monitored using three different techniques: water production monitoring, hydroxyl value calculation, and ATR-FTIR spectroscopy. In-line or off-line ATR-FTIR spectroscopy is a successful method for monitoring the reaction up to medium conversion and for monitoring composition in polyglycerol hydrogel production.
