Synthesis of Super Water-absorbent Resin

Zhu Yi-fei

Abstract

A super water-absorbent resin was systhesized from the sodium salt of acrylic with acrylamide as comonomer.N,Nˊ-methylenebisacrylamide as crosslinking agent.(NH4)2S2O8 and NaHSO3 as initator by means of orthogonal experiment.The effects of initator concentration,crosslinker content,AM content and neutralization degree of acrylic acid to the capabilities of the super water-absorbent resin were studied.The resin obtained 1 297 g/g and 90 g/g is distilled water and 0.9% NaCl solution,respectively.
