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. The use of CuBr / N,N,N<IMGSRC="/giflibrary/12/prime.gif"BORDER="0">,N<IMGSRC="/giflibrary/12/prime.gif"BORDER="0"><IMGSRC="/giflibrary/12/prime.gif"BORDER="0">,N<IMGSRC="/giflibrary/12/prime.gif"BORDER="0"><IMGSRC="/giflibrary/12/prime.gif"BORDER="0">-pentamethyldiethylenetriamine (PMDETA) as co-catalyst system results in a polymer free of halogen due to hydrogen transfer from PMDETA to the growing polymer chain. 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.
