Abstract: In this work, ultrasonic induced microemulsion polymerization of MMAwas successfully performed and the monomer conversion reached about 90% in 40 min. TEMobservation showed that the average diameter of PMMAlatex was 365 nm with a narrow distribution. Several influencing factors such as power output, surfactant, co emulsifier, monomer and chemical initiator were investigated detailedly from the view of formation of microemulsion and the growth of latex by spectraphotometry.
