N2 - Coupling atom transfer radical polymerization (ATRP) and coordination-insertion ring-opening polymerization (ROP) allows access to well-defined poly(methacrylate)-g[poly(ester)/poly(ether)] graft terpolymers according to a twostep procedure. In the first step, the controlled copolymerization of methyl methacrylate (MMA), 2-hydroxyethyl methacrylate (HEMA) and poly(ethylene glycol) methyl ether methacrylate (PEGMA) was carried out by using ethyl 2-bromoisobutyrate and NiBr2(PPh3) 2 as initiator and catalyst, respectively. The second step consisted of the ringopening polymerization (ROP) of ε-caprolactone (CL) or L,L-dilactide (LA) initiated by poly(MMA-co-HEMA-co-PEGMA) in the presence of either tin (II) bis(2-ethylhexanoate) (Sn(Oct)2) or triethylaluminum (AlEt3). The resulting graft copolymers as well as the intermediate poly(MMA-co-HEMA-co-PEGMA) terpolymers proved to be efficient surfactants as evidenced by dynamic interfacial tension measurements.
