Poly(acrylate-co-acrylamide)(PAAM) superabsorbent was prepared from partly- neutralized acrylic acid(AA) and acrylamide(AM) by inverse suspension polymerization. Its chemical structure and thermal property were characterized by Fourier-transform infrared spectrophotometer(FTIR) and the thermogravimetric analysis(TGA). The effects of various salt solutions on the absorbencies were studied systemically. Under the same ion strengths, the absorbencies of PAAM were in the order LiCl>NaCl>KCl in MCl (M=Li, Na, K) solutions and NaBr>NaCl>NaF in NaX solution, respectiverly. The tendency of absorbency of PAAM for the alkaline earth metal salt solutions was in the order MgCl2>CaCl2>BaCl2. PAAM resin is thermal stable before 320°C.
