- Abstract:
- This article describes a method for carrying out
emulsion copolymerization using an automated synthesizer.
For this purpose, batch emulsion copolymerizations of styrene
and butyl acrylate were investigated. The optimization of the
polymerization system required tuning the liquid transfer
method, sufficient oxygen removal from the reaction medium
and setting a proper sampling procedure. The monomer conversion-
time plots obtained with gas chromatography revealed
a good reproducibility of the automated reaction kinetics. Furthermore,
the particle size distributions and the properties of
the final products were found to be highly reproducible. The
performance of the automated reactions was subsequently
compared with the conventional ones: similar reproducibility
of either synthetic method was observed.
