Özet

Emulsion polymerization of vinylacetate was studied to monitor the reaction on-line by the near infrared FT-Raman technique. The experimental conditions for monitoring the reaction by Raman spectroscopy were determined and discussed with regard to their applicability to industrial production of the polymer. The reaction goes to approximately 90% completion in 50 min and the polymerization can be succesfully monitored by taking full-scan measurements between 20-3500 cm(-1) at every 8 min.
