- Well-defined PEGylated zwitterionic triblock copolymer, poly(ethylene glycol)-b-poly¬¬¬¬(methacrylic acid)-b-poly(2-aminoethyl methacrylate) (PEG-b-PMAA-b -PAEMA), was prepar¬e¬d from poly(ethylene glycol)-b-poly(tert-butyl meth acrylate) -b-poly(N-(tert-butoxycarbonyl)¬¬¬¬ amino ethyl methacrylate)(PEG-b-PtBocMA-b-PtBoc AEMA) precursor synthesized via atom tra¬ns¬e¬r radical polymerization (ATRP) by successively polymerized tert-butyl methacrylate (tBocM¬A) and N-(tert-butoxy- carbonyl) amionethyl methacrylate (tBocAEMA) monomers using a PEG-bas¬e¬d macro- initiator followed by t-Boc group deprotection. The obtained triblock copolymer was conf¬ir¬med by proton nuclear magnetic response (1H NMR) and Gel Permeation Chromatography (GPC). The resultant PEG-b-PMAA-b-PAEMA copolymer bearing a large number of amine moiet¬i¬es will have potential applications as anti-cancer drug or DNA carriers.
