Poly(acrylic acid-glycidyl methacrylate)[P(AA-GMA)] was synthesized by means of copolymerization of acrylic acid(AA) and glycidyl methacrylate(GMA) with potassium peroxydisulfate as an initiator and water as the dispersed phase, then with the action of crosslinking agent ethylene diamine(EDA), oxygen heterocycle of P(AA-GMA) were opened and crosslinked to form superabsorbent. The polymer was characterized by ~1H NMR and IR. The relationship between molar ratio[n(EDA) ∶n(GMA)] and absorbability was studied by tea-bag method. The results showed that the maximum absorbability of superabsorbent reached 527 times when n(EDA) ∶ (GMA)=1.0 ∶ 1.4.
