제목 Improvement of absorption properties by formation of surface pores using chemical blowing agent
초록 Superabsorbent polymers (SAPs) is synthetic polymeric materials used in disposable hygiene products due to its ability to absorb and retain large volumes of aqueous solutions. Recently, there has been an increasing demand for thin diapers, which requires excellent absorption performance and absorption rate of SAP. The most common approach to increasing absorption rate is to introduce pores inside SAP particles. In this study, we used chemical blowing agent during surface crosslinking process of poly(itaconic acid) based core SAP particles to introduce additional pores on the surface of the SAP particles. The surface pores were expected to improve absorption rate while maintaining or improving absorption performance of the SAP particles.
