Özet

Purpose: The aim of the research is to synthesize and characterize a new monomer and copolymer, and to investigate its thermal properties. Also, the reactivity of the monomers in the copolymer synthesized in this work was also investigated. Theory and Methods: Synthesis and characterization of monomer, homopolymer and copolymer were carried out. The heat behavior of the polymers was investigated. The monomer reactivity ratios of the copolymers synthesized at low conversion were calculated by Elemental Analysis. Results: Polydispersity of the homopolymer was found to be close to the individual. When TGA analyzes were performed to determine the thermal properties of the polymers, it was found that the thermal stability of the polymers increased with the addition of another acrylate derivative. The linear methods Kelen Tüdos and Fineman Ross and the nonlinear method were found to be r1.r2≈0,61 by the RREVM method. Conclusion: The monomers were successfully synthesized. As the amount of methyl methacrylate in the copolymers increases, the thermal stability of the copolymer also increases. It was observed that the synthesized copolymers exhibited the ideal copolymer behavior.
