Abstract
In this study, 4-diethanolaminomethyl styrene (DEAMSt) and benzyl methacrylate (BMA) copolymer were synthesized. The synthesized copolymer was characterized by spectral techniques such as FT-IR, 1 H-NMR, Elemental analysis, SEM, XRD, DSC and TGA. This copolymer obtained is used as ligand and its metal complexes were prepared with Co (II), Ni (II) and Zn (II) metal ions. The copolymer-metal complexes were characterized by the above spectral techniques. In addition, magnetic measurements of copolymer-metal complexes were received. The geometric structures of the copolymer-metal complexes according to magnetic measurements were estimated that have a tetrahedral geometric structure. The ligand was found an amorphous structure and metal complexes were found to be crystal structure by XRD analysis. The composition of the copolymer was determined by 1 H-NMR spectra and the composition of DEAMSt% was found as 23%. The average molecular weights and polydispersity index of the (DEAMSt0.23-ko-BMA) polymer were determined by gel permation choromatography. Glass transition temperature and thermal behaviors determined by DSC and TGA. The dielectric properties of ligand and copolymer metal complexes were investigated as a function of frequency.
