In this study, Schiff base was synthesized from the reaction of 4-carboxybenzaldehyde and 4-amino-3-methyl. Then, the obtained Schiff base was acted with aromatic and aliphatic dihalogen compounds in argon environment, and the polymers containing both ester and ether groups were obtained. For the structural analyses of synthesized substances FT-IR and NMR analysis, for the optical properties fluorescence and UV-Vis measurements, and for the thermal analyses TG-DTA and DSC techniques were used. In addition, electrochemical and electrical conductivity measurements were carried out. Aromatic imine polymers and their derivatives were already synthesized, and the properties such as high thermal resistance, low band gap and semi-conductive properties were also described in literature. In this study, new kinds of polymers synthesized are expected to have a high thermal resistance with elastic aliphatic and conjugated aromatic groups. The effects of the presence of etheric bonds and ester groups in the main chain of the polymers on several physical and thermal properties are also aimed to be explored. (C) 2015 The Authors.
