高吸水性聚合物是交联的聚电解质。由于它们的离子性质和相互连接的结构，它们吸收大量的水和其他水溶液而不溶解。这使得它们非常适合作为当今销售的许多个人护理产品中的体液吸收剂，包括婴儿尿布、成人失禁产品和女性餐巾。几个新兴的应用程序也被描述。一个简单的实验室制备的部分中和，交联聚（丙烯酸）是沿着与测试方法，适用于测量产品的吸收能力。描述了证明溶胀凝胶做功的能力以及凝胶排除大分子溶质扩散到其多孔交联结构中的能力的实验。
Superabsorbent polymers are cross-linked polyelectrolytes. Because of their ionic nature and interconnected structure, they absorb large quantities of water and other aqueous solutions without dissolving. This makes them ideally suited as absorbents of body fluids in many personal care products sold today, including baby diapers, adult incontinence products, and feminine napkins. Several emerging applications are also described. A simple laboratory preparation of partially neutralized, cross-linked poly(acrylic acid) is given along with test methods suitable for measuring the absorption capacity of the product. Experiments are described that demonstrate the ability of a swelling gel to perform work, and the ability of a gel to exclude macromolecular solutes from diffusing into its porous, cross-linked structure.
