Atom transfer radical polymerization (ATRP); Dodecyl acrylate; N-(Alkyl)-2-pyridylmethaminine; Synthesis
A facile synthesis of poly(lauryl acrylate) has been achieved by atom transfer radical polymerization using benzyl-2-bromoisobutyrate. copper (I) bromide, and N-(n-octyl)-2-pyridylmethanimine (OPMI). The latter was of great interest as its synthesis was very easy to carry out and as it allowed the reaction mixture to be homogeneous, which was essential for the control of the reaction. The polymerization was controlled under these conditions and was optimized with the addition of copper (II) bromide as deactivator. We proved that the synthesis of poly(lauryl acrylates) with well defined molecular weights and narrow polydispersities was possible using a ligand which does not require difficult synthesis and purification. We also showed the ability of pyridylmethanimine ligands to control ATRP of an acrylate derivative. Best results were obtained at 130 degrees C in xylene for [Initiator](0)/[Cu(I)Br](0)/[Cu(II)Br-2](0)/[OPMI]/[lauryl acrylate] equal to 1/1/0.05/2.2/181, respectively (M-n = 19,942, DPI = 1.28).
