Abstract: We synthesized poly(methyl acrylate) by the method of single electron transfer living radical polymerization (SETLRP) and the method of atom transfer radical polymerization (ATRP). The properties of products were detected by ¹H-NMR, FT-IR and Ubbelohde viscometer. The results show that the molecular structure of the products synthesized by the two methods is similar, and the specific viscosity of the final product has little difference; in the same reaction time, the monomer conversion rate of SET-LRP method is much higher than that of ATRP method, and the SET-LRP reaction process  accords with the firstorder reaction kinetics.
