Redoks Polimerizasyonu ile Epoksi Reçine İçeren Poli(GMA-b-EG) Blok Kopolimerinin Sentezi ve Karakterizasyonu
In this study, poly(glycidyl methacrylate-block-ethylene glycol) [P(GMA-b-EG)] epoxy-based copolymer was synthesized and evaluated by redox polymerization. For this purpose, poly(GMA-b-EG) block copolymer containing epoxy-resin was synthesized by redox polymerization of glycidyl methacrylate using polyethylene glycol (PEG-3000) macroinitiator in the presence of cerium ammonium nitrate [Ce(NH4)2(NO3)6] catalyst. The synthesized epoxy-based copolymer was characterized by FTIR, 1H-NMR, DSC, TGA, and SEM spectroscopic methods. The molecular weight of the epoxy-based copolymer was also determined by GPC. The epoxy-based copolymer has a relatively narrow molecular weight and distribution. The DSC result showed that the glass transition temperature value of the epoxy-based copolymer was 28 oC, different from that of the homopolymer. SEM analysis showed that the surface morphology of PEG and epoxy-based copolymers was different. It has been proven by TGA analysis that the epoxy-based copolymer has two different decomposition temperatures of 160 °C and 400 °C.
