In the present work, the polymerization reaction of dimethylaminoethylenemethacrylate (DMAEMA) and morpholinoethylenemathacrylate (MOREMA) initiated with PEG-azo-initiator was carried out. The copolymer products obtained were characterized by IR- and NMR spectra. It was shown that the two copolymers synthesized were of good bacterial activity against Staphylocooccus aureus.
