摘　　要：由氯甲基化低交联聚苯乙烯和异氰尿酸在三乙胺作用下反应，制得了凝胶型交联聚苯乙烯-异氰尿酸树脂，测定了该树脂对苯酚和间苯二酚在不同温度下的吸附等温线，依据Clapeyron-Clausius方程从吸附等温线计算出了吸附热，从热力学的角度论证了树脂是基于氢键键合和疏水作用而吸附苯酚和间苯二酚的。Gel-type cross-linked polystyrene-isocyanuric acid resin has been obtained by reaction of chloromethylated polystyrene with isocyanuric acid under the existence of triethylamine. The adsorption isotherms of phenol and resorcinol onto the resin from aqueous solution have been measured. Adsorptive enthalpies of phenol and resorcinol onto the resins were calculated according to the Clapeyron-Clausius equation. A hydrogen-bonding assisted adsorption mechanism has been proposed on the point of thermodynamics.
