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, g of the polymer surface, and the specific enthalpy of adsorption, D , of probes on the polymer were also calculated. Lewis acid, , and Lewis base, , parameters of PVBC-Diethanol amine surface were determined. The values of and indicated that PVBC-Diethanol amine surface exhibited a basic behavior.
在本工作中，合成并表征了二乙醇胺改性的聚苯乙烯基聚合物（PVBC - 二乙醇胺），然后通过无限稀释反相气相色谱法研究了该聚合物的表面性质。基于极性和非极性探针与聚合物之间的相互作用得到的保留图绘制于30至55°C的温度范围内。通过这些图，还计算了聚合物表面自由能的色散分量、聚合物表面的γs以及探针在聚合物上的吸附比焓ΔH。测定了PVBC - 二乙醇胺表面的路易斯酸（γ+）和路易斯碱（γ-）参数。γ+和γ-的值表明PVBC - 二乙醇胺表面表现出碱性行为。
