Suspension polymerization for synthesis of new hypercrosslinked polymers nanoparticles for removal of copper ions from aqueous solutions

Abstract Novel hypercrosslinked polymers nanoparticles (HCPNs) were designed by suspension polymerization technique with high surface area as well HCPNs functional groups have the affinity to removal of copper ions from aqueous solutions. Two synthesized through a two-step reaction, initially including N-methacryloxytetrachlorophthalimide (NMTPA) divinyl benzene (DVB) give poly(NMTPA-co-DVB) and followed treatment poly(NMTP-co-DVB) triethylenetetramine (TETA) (1) tetraethylenepentamine (TEPA) (2). Using scanning electron microscopy transmission microscopy, morphology particles was detected, also, particle size measured. Also, chemical structures compounds illustrated Fourier transform infrared spectroscopy 1 H-nuclear magnetic resonance ( H NMR). Thermal stability characterized thermogravimetric analysis. The results that is in range 25–50 nm. reported for separation wastewater, which showed very good these wastewater.
