ATRP synthesis of polymethylmethacrylate with a new ligand

So far, many articles about ATRP polymerization method with various ligands and different uses have been published. Atom transfer radical polymerization (ATRP) mediated by Coppercomplexes is a powerful controlled radical polymerization technique for preparation of many well-defined polymers, butits catalyst residue remains challenging [1-5]. In this paper is described a comprehensive report on the ATRP method usinga new ligand called N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). This ligand gives special features to the synthetic catalyst in ATRP method.With these properties, we can review both homogeneous and heterogeneous polymerization. Different factors can be involved a usefulness of a catalyst in the ATRP. The firstfactor is a formation of the stable complexes between the two nitrogen groups of ligand and transition metal. Second factoris the ability to connect on the Silica nanoparticles for heterogeneous reactions and recycle of complex at the end ofreaction. In this work, AEAPTMS ligand was used in ATRP of methylmethacrylate (MMA) monomer. The results revealed that the polymer was obtained according to the ATRP method(Polymers with controlled molecular weight and narrow dispersion of molecular weight).
