Ultrasonic energy was used as a means of driving an acrylic polymerization to completion. The goal is that in the emulsion polymerization of these material, any unreactive monomer must be removed for environmental and health reasons. Results showed that ultrasonic energy is effective in causing a faster polymerization rate which results in a quicker removal of unreacted monomers. A lower monomer concentration (g/1000 ml) was achieved with ultrasonic polymerization.
