S uperabsorbent polymers (SAPs) are special polymeric
materials that can absorb large amounts of water, saline
solutions or physiological fluids as high as 10-1000 times
their own weight due to a considerable number of hydrophilic
groups in their structure. Recently, a major research trends
of SAPs are the relaxation of the gel-blocking phenomenon.
Surface cross-linking reduces gel-blocking and improves
absorbency under load (AUL). In this study, surface cross-
linking was achieved through thermal ring-opening reaction
with ethylene glycol diglycidyl ether (EGDGE) as a cross-linking
agent. We prepared carboxylated vinyl monomer based SAPs
with comonomer. However, the SAPs have low absorption
capacity under load (AUL) and low permeability. When EGDGE
is used for surface cross-linking agent, the SAPs formed core-
shell structure with different cross-linking densities between
the exterior and interior. As a result, AUL and permeability
of surface cross-linked SAPs were improved. We measured
the absorption properties of the surface cross-linked SAPs
according to the EGDGE input content, ratio of co-medium,
reaction temperature and reaction time
