Synthesis methacrylate polymers which containing barbituric acid and adsorption studies

In this study, St-MMA having malonester side group,copolymers that have different ratios were synthesized at 60°C in a 1,4-dioxane solution in the presence of AIBN by free-radical polymerization. These polymers were modified with urea and were synthesized poli(St-co-BAMA) that have different ratios. These polymers were characterized by FT-IR and 1H NMR.Dye uptake properties of polymers were investigated at room heat. Also dye uptake properties were investigated different temperature and results were compared.Dielectric properties of all polymers were measured at different frequencies by impedance analyzer. Dielectric permittivity and dielectric loss were measured at room heat and were compared with each other. In addition to dielectric properties of all polymers were measured at different temperature in constant frequences and were compared with each other.Termal measurements of all polymers were carried out by TGA and DSC. The activation energies were measured by TGA at different heating rate by Kissinger method.Keywords: Barbituric acid, Adsorption, Dielectric properties, Termal measurements
