S uper absorbent polymer (SAP) is a cross-linked hydrophilic
polymer. It can absorb, swell, and retain aqueous solutions
up to hundred times of its own dry weight. We synthesized
copolymers consisting of carboxylated vinyl monomer and vinyl
sulfonic acid using various crosslinking agent. Crosslinking
agent is needed to synthesize SAP and it has a direct effect on
the crosslinking density of the SAPs. As the amount of added
crosslinking agent increases, the cross-linking density of the
SAPs increases. This is related to absorbency. We synthesized
the SAPs using four types of acrylate based crosslinking agents
to compare absorption properties. As a result, only two of them
succeeded in synthesis and the rest did not proceed. Each
monomer was neutralized with sodium hydroxide to prepare
carboxylate ions. Polymerization was initiated by ammonium
persulfate added after the crosslinking agent addition. The
structures of the prepared polymers were confirmed by FT-IR
(Fourier transform infrared spectroscopy). We have measured
SAP’s properties such as centrifuge retention capacity (CRC)
and absorbency under load (AUL) in 0.9 wt.% saline solution
depending on the reaction time, reaction temperature or the
amount of the crosslinking agent. We studied the effect of
each crosslinking agent on the SAP absorption properties.
