Study on Polymerization and Absorbency of Acrylic-Based Polymer

Acrylic-Based Polymer(PAAS) was synthesized by aqueous solution polymerizatioin. The influences of monomer concentration, the neutralization, the concentrations of crosslinker, initiator, and the reaction temperature on the absorbency of PAAS were studied, the results showed that the absorbency was of PAAS 1430g/g in distilled water, and 102g/g in 0.9 wt% NaCl solution. The absorbencies of PAAS in different ionic strength of NaCl, CuCl_2, FeCl_3 and MgCl_2,CaCl_2,BaCl_2 and KCl, KBr, KI solutions were given, and the absorbency decreased with an increase of strength in different salt solutions.
