摘要：
Poly(acrylamide-co-itaconic acid) (P(AM-co-IA)) hydrogel microspheres were prepared via inverse suspension polymerization method. DLS results showed the formation of the monodispersed hydrogel microspheres. The size of the hydrogel microspheres could be controlled by polymerization parameters. Absorbencies of P(AM-co-IA) microspheres in water and saline were investigated and calculated by size changes of each particle before and after swelling. The results showed that P(AM-co-IA) had high absorbencies, the weight of swollen particles was above 4000 times to that of the original dried microspheres. The superabsorbent hydrogel microspheres might find the potential applications in the fields of soil amendments, water shutoff agents, and drug delivery carriers.
