✦ Synopsis

The inverse microemulsion polymerization of 2-methacryloyl oxyethyl trimethyl ammonium chloride (MADQUAT) in a continuous stirred tank reactor is investigated. The effect of removing the oxygen from the feed tank, initiator concentration, aqueous phase volume/emulsifier volume ratio, and residence time on the monomer conversion, particle size, and molecular weight was investigated. The removal of the oxygen allowed high conversions with moderate amounts of initiator to be obtained. In general, the process did not present oscillations.
