| Abstract: | A novel poly(acrylic acid-co-acrylamide)/diatomite superabsorbent composite was synthesized by using N,N'-methylenebisacrylamide as a crosslinker and ammonium persulfate as an initiator in aqueous solution.The effects of the amount of acrylamide,initiator,crosslinker,degree of neutralization of acrylic acid,and diatomite concentration on water absorbency were investigated.The optimum reaction conditions were:neutralization degree,70%;acrylamide,20%;diatomite,10%;initiator,0.9%;crosslinker,0.15%,respectively... |
