Synthesis and characterization of zwitter ion functionalized Poly(styrene) based random co-polymer: One pot method

The main target of the present research work is fabrication of low-cost poly(styrene) based membrane towards water filtration purpose.A zwitter ion functionalized poly(styrene) based random co-polymer was synthesized by one pot method.Acid and amine functionalized styrene-based co-polymer was synthesized by a free radical solution polymerization method in the presence of dicumylperoxide as a lone chemical initiator by one pot method under N2 atmosphere with vigorous stirring.The zwitter ion functionalization of styrene monomer was carried out through Friedel-Crafts alkylation method.The synthesized random copolymer was characterized using FT-IR, 1 H-NMR spectra, DSC, TGA, SEM, EDX, GPC, XPS, WCA, POM and XRD techniques.The tensile strength of the copolymer was tested.The FT-IR spectrum showed a peak corresponding to C-N stretching and O-H stretching.The DSC showed the highest Tg of 96.9 o C for the styrene based random copolymer.
