Özet

© 2021 TUBITAK. All rights reserved.In the present work, diethanol amine modified polystyrene based polymer (PVBC-Diethanol amine) was synthesized and characterized, then surface properties of the polymer were examined by inverse gas chromatography method at infinite dilution. The retention diagrams obtained based on the interaction of polar and nonpolar probes with the polymer were drawn over a temperature range from 30 to 55°C. Through the diagrams, the dispersive component of the surface free energy, gSD of the polymer surface, and the specific enthalpy of adsorption, DHAS , of probes on the polymer were also calculated. Lewis acid, KA, and Lewis base, KD , parameters of PVBC-Diethanol amine surface were determined. The values of KA and KD indicated that PVBC-Diethanol amine surface exhibited a basic behavior.
