We successfully synthesized Poly(styrene-co-maleic anhydride) (PSMA) by using the co-polymerization system of styrene and maleic anhydride monomer. Then, PSMA-PEI copolymer was synthesized by reaction between PSMA copolymer and NH2 bond of Polyetyleneimine (PEI). The molecular weight is changed by controlling the amount of styrene, maleic anhydride and PEI was analyzed by GPC. PSMA-PEI copolymer was characterized by using FT-IR and 1H-NMR spectra. Also, the thermal property of PSMA-PEI copolymer was confirmed by DSC and TGA analysis. |
