Chemical functionalization of cellulose-poly (glycidyl-methacrylate) graft copolymer with two different poly amino compounds

Abstract

Two amino-functionalized cellulose-poly(glycidyl methacrylate) graft copolymers (AM-CPGMA), based on waste cotton fibers, were preparedby the aminization of selected cellulose-poly(glycidyl methacrylate) graft copolymer (CPGMA) produced at best polymerization conditions using diethylenetri-amine (DETA) and triethylenetetraamine (TETA). The different aminization parameters, namely the aminating agent/epoxy molar ratio, reaction time, liquor ratio, pHand temperature were investigated, and optimum reaction conditions were established. The two prepared amino-functionalized cellulose-poly(glycidyl methacrylate) graft copolymers (AM-CPGMA) were characterized by the FT-IR, thermal gravimetric analysis (TGA), surface area measurement using Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) theories and scanning electron microscope (SEM). Thus obtained results were compared with the native cellulose and its graft copolymer.
