Method for producing super absorbent polymer and super absorbent polymer
The present invention relates to a super absorbent polymer having a controlled degree of internal crosslinking and thereby having simultaneously improved basic absorption capacity and absorbency under pressure, and a method for producing the same. The super absorbent polymer may comprise a base polymer powder including a cross-linked polymer of a monomer containing a water-soluble ethylenically unsaturated compound or its salt; and a surface cross-linked layer that is formed on the base polymer powder and is further cross-linked from the cross-linked polymer, wherein a glass hollow particle having a micron-scale particle size is included in the cross-linked structure of the cross-linked polymer of the base polymer powder.
