In this study, starch chloroacetate (St.ClAc) as a macro-initiator was firstly prepared by the reaction of chloroacetyl chloride with primary OH groups on powder starch. Cu(I)Cl and 2,2’-bipyridine were used as a transition-metal compound and as a ligand, respectively. The graft copolymerization of starch was made with our own synthesized N-(4-nitrophenyl)acrylamide (NPA) monomer by method of atom transfer radical polymerization. St.ClAc macro-initiator and its graft copolymer (St.ClAc-g-NPA) were characterized by FT-IR spectra and elemental analysis. Starch, synthesized St.ClAc and its graft copolymer with NPA were tested for its antimicrobial activity against bacteria and yeast.
