Radical polymerization of methacrylic acid (MAA) (I) in the presence of polyacrylamide (PAM) (II) in water has been investigated to clarify the polymer effect of the added II. It was observed that the presence of II affects on the polymer yield and molecular weight in the polymerization of I. From conductivity and turbidity measurements, it was found that II interacts with I monomer and polymer through an electrostatic force, hydrogen bonding, or hydrophobic bonding. The observed effects of the concentrations of PAM, MAA, and potassium persulfate initiator on the rate of the polymerization were discussed on the basis of these interactions. The polymerization of acrylamide in the presence of the polymer of I was also studied. Some properties of the polymer complex isolated were determined.
