根据Wikipedia，Superabsorbent聚合物（SAP）是可以吸收和保留大量液体的聚合物。吸水聚合物在交联后被分类为水凝胶，通过与水分子键合氢粘合剂吸收水溶液。SAP吸收水的能力是水溶液离子浓度的一个因素。在去离子和蒸馏水中，SAP可能会吸收其重量500倍（从自身体积的30-60倍），并且可能会达到99.9％的液体，但是当放入0.9％的盐水溶液中时，吸收率会下降至50倍它的重量。溶液中的价阳离子的存在将阻碍聚合物与水分子结合的能力。总吸收和肿胀能力受到制造凝胶的交联类型和程度控制。低密度交联SAP通常具有较高的吸收能力，并且膨胀得多。这些类型的SAP还具有更柔软，更粘的凝胶形成。高的交联密度聚合物表现出较低的吸收能力和膨胀，但是凝胶强度更牢固，即使在适度的压力下也可以保持颗粒形状。 The largest use of SAP is found in personal disposable hygiene products, such as baby diapers, adult protective underwear and sanitary napkins. SAP is also used for blocking water penetration in underground power or communications cable, horticultural water retention agents, control of spill and waste aqueous fluid, artificial snow for motion picture and stage production.

巴斯夫已经公布了可再生原料的HYSORB®B7015MB superabsorbent polymer. The new range includes HySorb®new odor control and HySorb®Mass Balance approach, binders for fibrous materials and of additives for hygiene, filtration and medical applications. The pioneering odor control superabsorbent polymer HySorb®除了巴斯夫的Superabsorbent聚合物产品组合外，还可以改善失禁者的生活质量。通过阻断氨的形成，它可以防止长时间尿液引起的气味。此外，其高吸收能力有助于保持皮肤干燥。超吸收性聚合物用于我们生活中每天需求的各种应用。成人尿失禁市场仅次于婴儿护理超级吸引人，并且经历了全球最高的增长。
歇斯底空®B7015MB - the new superabsorbent polymer based on renewable feedstock: Working in cooperation with TÜV SÜD (a third-party certification body), BASF has developed an innovative mass balance approach for the use of renewable based feedstock in the BASF "Verbund". Based on this approach, biomass is fed into existing plants at the very beginning of the production chain of superabsorbents. This biomass share is then allocated to sales products according to their recipes using the new standard including 3rd party certification of the product. The quality of the superabsorbent polymers remains unchanged. Biomass equivalent can be allocated to superabsorbents up to 100% according to this standard driven by its customers' specifications and demand, which can be marketed accordingly. Existing plants and technologies along the value chain can continue to be used, and the customers' product designs and production process require no adjustments. The superabsorbent polymers based on renewables save fossil based raw materials and reduce greenhouse gas emissions, thereby contributing to sustainable development. BASF continues with its expertise in the field of polymer dispersions for fiber bonding with tailor made solutions to customers in the construction, furniture and automobile industry. The dispersions are characterized by high functionality and customized processability. Innovative and intelligent solutions made by BASF in the field of non-wovens help to make the customers' products more efficient, competitive and eco-friendly. One focus in the field of dispersions for fiber bonding is the ecologically compatible reactive resins of the Acrodur®品牌。Acrodur®，水性交联丙烯酸酯树脂是具有出色结合特性的环保单组件系统。基础技术基于多功能酒精的聚羧酸的热交联。与经典的反应性树脂不同，在交联过程中没有释放有机物质，例如苯酚或甲醛。固化引起的唯一副产品是水。Acrodur®既不是象征性的也不是爆炸性的，因此可以保证环境友好，也可以安全而简单。结合剂不仅改善了成品的特性，还可以确保生产过程中的安全工作条件。此外，环境兼容的技术可帮助加工公司尊重排放限制并节省成本。
