Abstract

A polymer may be an absorbent polymer used for forming a so-called SAP. Through adjustment of materials applied to a cross-linking process for forming the SAP, and conditions of the cross-linking process, such a polymer may be formed even without using a so-called cross-linking agent or by minimizing its used amount, thereby exhibiting excellent absorption capacity. The polymer may be formed by cross-linking a biodegradable material, even without using the cross-linking agent or by minimizing the same, thereby exhibiting the maximum biodegradability of the material.
