PPM amount of Fe(iii)-mediated ATRP of MMA with phosphorus-containing ligands in the absence of any additives

Abstract

MMA was polymerized via new oxidation-free ATRP by using ppm amounts of a Fe(III)-mediated ATRP system with four phosphorus containing ligands without any external reducing agent or free radical initiator. Well-controlled polymerizations were able to be achieved to produce PMMA with a high molecular weight (>300 000) and low polydispersity (PDI < 1.3) with a 10 ppm amount of FeBr₃.
