The Kaolin/(AA-AM-DMC) superabsorbent resin with cationic monomer, nonionic monomer and anionic monomer was prepared by inverse suspension method, using cyclohexane as continuous phase, N, N-methylene-bis-acrylamide as crosslinking agent, potassium persulfate as initiating agent, Span 60 as dispersing agent. The effect of the degree of neutralization of acrylic acid, Kaolin amount, DMC amount, initiating agent amount, crosslinking agent amount, and polymerization temperature were investigated. The superabsorbent resin was characterized by IR spectroscopy and SEM. Water absorption rate under the optimal conditions can reach 1827g/g and salt absorption rate can reach 146g/g.
