SYNTHESIS AND PREPERTIES OF SUPER WAYER-ABSORBING RESIN CONTAINING NITROGEN,PHOSPHORUS AND POTASSIUM

Tian Wei-ping

Abstract

High water-absorbing and water-keeping super absorbent was synthesized by graft copolymerizing the phosphate starch with sodium acrylate and potassium acrylate in presence of persulfate potassium as initiator.The influences of the counteract degree of the acrylic acid on the water absorbability were studied.Through experiments the good condition for the water-absorbing and water-keeping super absorbent was got.
