| Abstract: | Poly (acrylate-co-acrylamide) high water absorbent resin was obtained by inverse suspension polymerization (ISP) using monooctadecyl phosphate as dispersing agent. The polymerization system was stable. The polymer can be obtained in the form of particles by filtering and drying without evaporating the solvent. The influence of polymerization conditions on the physical states of the polymer, deionized water-absorbency (DWA) and saline solution absorbency (SSA) has been discussed. The copolymer can absorb 680 times their weight of distilled water and 86 times their weight of saline solution (0.9%). |
