An efficient, heterogeneous, reusable atom transfer radical polymerization catalyst

Abstract

Melamine based porous polymer (MPP) was prepared as a template solid to incorporate Cu(I) cations into the framework through chelating with nitrogen groups of the melamine. The copper integrated porous material (Cu(I)@MPP) was used as a heterogeneous catalyst and displayed high activity in copper catalyzed atom transfer radical polymerization of methyl methacrylate. The characterization of the Cu(I)@MPP was performed using nitrogen adsorption experiments and wide-angle X-ray and Fourier transform infrared spectroscopies. The atomic absorption spectroscopy measurements confirmed that the catalyst is practically non-leaching and Cu(I) was found to be below 20ppb after each atom transfer radical polymerization. Moreover, the catalyst showed reusability without any significant change in its activity. (c) 2017 Society of Chemical Industry
