摘要: A great challenge in controlled radical polymerization such as atom transfer (ATRP) has been related to keep the livingness and molecular weight control of reaction at high conversion, especially bulk polymerization. The objective this work is investigate effects ultrasound power on conversion. initiator for continuous activator regeneration ATRP used methyl methacrylate (MMA) model system. Good up conversion are obtained through employing ultrasonic waves. By method, MMA polymerized “glass state” (88%) 70°C with polydispersity about 1.2 under an operating frequency 40 kHz output 100 W. Chain extension proves synthesized polymers glassy state. © 2016 American Institute Chemical Engineers AIChE J, 62: 1683–1687,
