Preparation of High Water-Absorbent and Study of the Influence of Crosslinking Agent on Water-Absorbency |
| |
| Abstract: | The water-absorbent (polyacrylate crosslinking with polyethyleneglycol diacrylate) was synthesized by inverse suspension polymerization process and slow dripping addition of monomers to dispersing medium.The influence of such factors as temperature, initiator concentration, monomer concentration, and volume ratio of oil phase to water phase on the absorbency of water-absorbent has been discussed in detail. The chain length of the crosslinking agent had a great effect on the absorbency and absorption rate of water-absorbent. As the molecular weight of polyethyleneglycol was 600,the water-absorbent possessed maximum water-absorbency, absorbing 1150 times distilled water and 125 times saline solution (0.9% NaCl). |
