Abstract

In this study, 1-octadecene-alt-maleic anhydride (OC-MA) copolymer was synthesized by radical polymerization method. The synthesized copolymer was first time modified with ammonia, methylamine, aniline and hexamethylenediamine reagents in acetone environment. The modified amidic acid derivatives were divided into two parts as quantity. One of these amounts was dried as an amidic acid derivative, and the other was imidized in dimethylformamide environment with constant stirring at 150 °C for 5 hours. Structural characterizations of the obtained samples were determined from the FTIR spectra. Thermal stability was compared from Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) curves. It was established that the modified copolymers were thermally more stable than that of the original OC-MA copolymer. However, it was observed that the size of the molar masses of the reagents participating in the modification reactions showed linear or parabolic increases according to thermal parameter temperature of the decomposition reaction obtained from the TGA and DSC curves.
