摘要: Atom transfer radical copolymerization of methyl methacrylate (MMA) and (meth)acrylate-terminated poly(lactic acid) (PLA) macromonomers was investigated. The relative reactivity methacrylate-terminated macromonomer (1/rMMA = 1.75) acrylate-terminated 0.61) close to that 2-hydroxyethyl acrylate, respectively. difference in ATRP conventional polymerization is discussed terms the diffusion control effect. A mixture copolymerized with MMA by give a homogeneously branched PMMA-g-PLA graft copolymer low polydispersity (Mw/Mn 1.15).
