Grafting of Starch: Synthesis and Thermal Properties

Nevin Cankaya

Abstract


Starch chloroacetate (St.ClAc) as a macro-initiator was pre-synthesized with reaction of primary OH groups on powder starch and characterized. In this study, the graft copolymer of St.ClAc with the previously synthesized 2-(4-methoxyphenylamino)-2-oxoethyl methacrylate (MPAEMA) and N-cyclohexylmethacrylamide (NCMA) monomer was made by atom transfer radical polymerization method (ATRP). St.ClAc and its graft copolymers (St.ClAc-g-MPAEMA and St.ClAc-g-NCMA) were characterized by FT-IR spectra and elemental analysis. In addition, thermal stability of these new graft polymers was also investigated, and compared to each other.
