Özet:

 In this study, polyglycidyl methacrylate-block-ethylene glycol PGMA-b-EG epoxy-based copolymer was synthesized and evaluated by redox polymerization. For this purpose, polyGMA-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 CeNH42NO36 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.

 Bu çalışmada, poliglisidil metakrilat-blok-etilen glikol PGMA-b-EG epoksi bazlı blok kopolimer redoks polimerizasyonu ile sentezlendi ve değerlendirildi. Bu amaç için, polietilen glikol PEG-3000 makrobaşlatıcı kullanılarak glisidil metakrilatın seryum amonyum nitrat CeNH42NO36 katalizörü varlığında redoks polimerizasyonu ile epoksi reçine içeren poliGMA-b-EG blok kopolimeri sentezlendi. Sentezlenen epoksi bazlı kopolimer FTIR, 1H-NMR, DSC ve SEM gibi spektroskopik yöntemlerle karakterize edildi. Epoksi bazlı kopolimerin moleküler ağırlığı da GPC ile belirlendi. Epoksi içeren kopolimer, nispeten yüksek molekül ağırlığına ve dar molekül ağırlığına dağılımına dispersity sahipti. DSC sonucu, epoksi bazlı kopolimerin camsı geçiş sıcaklığı değerinin homopolimerden farklı olarak 28 oC olduğunu göstermiştir. SEM analizi, PEG ve epoksi bazlı kopolimerlerin yüzey morfolojisinin farklı olduğu söylenebilir. Epoksi bazlı kopolimerin 160 C ve 400 C gibi iki farklı ayrışma sıcaklığına sahip olduğu TGA analizi ile kanıtlanmıştır.
