ABSTRACT
We would like to understand the role of PMA chains in the formation of hydrogels. The PMA chains had the possibility of ionic interaction and cross-linking between them. Addition of inorganic salt with various metal cations may be suitable method. So, the effect of inorganic salt on gelation of PMA and PMB aqueous solutions was studied. We selected three kinds of inorganic salt, NaCl, CaCh and FeCl3.
