英文摘要	a novel poly(acrylic acid)/sodium humate superabsorbent composite was synthesized by aqueous solution polymerization of acrylic acid using n, n'-methylenebisacrylamide as a crosslinker and ammonium persulfate as an initiator in the presence of sodium humate. the effects on water absorbency such as initial monomer concentration, degree of neutralization of acrylic acid, amount of crosslinker, initiator and sodium humate, etc. were investigated. the water absorbency of the superabsorbent composite synthesized under optimal synthesis conditions with a sodium humate content of 20% exhibited an absorption of 1268 g h2o/g sample and 93 g h2o/g sample in distilled water and in 0.9 wt% nacl solution, respectively. swelling rate and water retention tests were also carried out. the results show that sodium humate, as a kind of functional filler, can enhance comprehensive properties of superabsorbent composite and reduce the product cost significantly. copyright (c) 2005 john wiley & sons, ltd.
