摘　　要：强酸型阳离子交换树脂在许多领域有着重要用途。交换容量是影响树脂应用效果的重要参数,更高的交换容量往往赋予树脂更好的应用性能。本文探讨了高交换容量强酸型阳离子交换树脂的合成方法,结合致孔剂对聚合物内部物理结构的影响机理,采用在单体中加入少量致孔剂的方法得到改性的苯乙烯-二乙烯苯共聚物,再经磺化制备树脂。通过实验优化,得到了钠型交换容量为4.82 mmol/g(干树脂)的凝胶型树脂(交联度为7%),且机械强度好。Strong acid cation exchange resin has many important applications in most fields. Exchange capacity is an important parameter which influences the effect of the resin applied, the better performance of the resin due to its higher exchange capacity mostly. In this paper, the method of synthesis of strong acid cation exchange resin with high exchange capacity was discussed. Based on the influence of the pore-forming agent on the physical structure of the polymer, a small amount of the pore-forming agent was added to the monomer to modify the styrene-divinylbenzene copolymer which was then sulfonated to form the resin. The Na-type exchange capacity of 4.82 mmol/g （dried resin） of the gel type resin （the crosslinkage is 7%） with good mechanical strength was obtained while the experimental optimization was adopted.
