Abstract: Super absorbent resin has been synthesized through solution polymerization in this study. Cotton flock fibers were used as raw material and modified with chloroacetic acid to obtain carboxymethyl cellulose (CMC). Thereafter, the super absorbent polymer (SAP) was synthesized through grafting copolymerization of CMC with acryl acid (AA) and acrylamide (AM) using N,Nmethylene biscrylamide (MBAA) as crosslinker. The prepared super absorbent resin could absorb more than 2500 times of deionized water and 310 times of 0.9% NaCl solution. It became transparent colloid when fully wetted with deionized water.
