摘　　要：以大孔强碱树脂为母体树脂,用硫酸进行磺化反应,合成两性树脂.考察了硫酸浓度,反应时间,反应温度对树脂吸附量的影响,找出了较好的合成条件,在此条件下合成的两性树脂显示了较好的硬水软化能力和热水再生性能.Amphotenc resins are synthesized by sulfonate of strong base resin. The influences of concentration of vitriol, reaction time and temperature on adsorption and desorption of amphoteric resins are studied. The optimum synthesis condition is achieved. The amphoteric resins prepared under these conditions exhibit good ability in water softening and their own regeneration.
