Abstract In order to obtain amino-terminated polymethyl methacrylate (PMMA-NH<SUB>2</SUB>) free of halogen we used the atom transfer radical polymerization (ATRP) to polymerize methyl methacrylate (MMA) in presence of an initiator containing an alkyl bromide unit and a protected amine functional group.

However, side reactions occur affecting the typically <IMGSRC="/giflibrary/12/ldquo.gif"BORDER="0">living<IMGSRC="/giflibrary/12/rdquo.gif"BORDER="0"> character of the ATRP. The measured molecular weights are consistently higher than the theoretical ones and the molecular weight distributions are relatively broad.
