摘要
A method of surface cross-linking superabsorbent polymer particles using UV irradiation is provided. The superabsorbent polymer particles for use in the method have a relatively high degree of neutralization. Brønsted acids are selectively applied onto the surface of the superabsorbent polymer particles to selectively facilitate a relatively high number of protonated carboxyl groups at the surface of the superabsorbent polymer particles while the relatively high degree of neutralization in the core of the superabsorbent polymer particles remains substantially unaffected.
