英文摘要	With the natural guar gum(GG), montmorillonite modified by cetyl trimethyl ammonium bromide (OMMT), acrylic acid(AA) as raw materials, ammonium persulfate as initiator, N,N'-methylene bisacrylamide as crosslinker agent, novel guar gum-g-poly(acrylic acid)/OMMT(GG-g-PAA/OlVfMT) superabsorbent composites were prepared by graft polymerization in aqueous solution. The effect of the content of OMMT on the water absorbency and the swelling rate of the superabsorbent composites was studied. Water-retention properties and reswelling capabilities of the superabsorbent composites were also investigated. The results from FT-IR spectra showed that GG and OMMT participated in graft polymerization reaction with AA. The introduced 5% OMMT enhanced the water absorbency and the swelling rate of superabsorbent composites, improved reswelling capability. With the increase of the proportion of OMMT, the swelling rate of superabsorbent composites accelerated at the range of experiment research.
