Complex formation in aqueous system between methyl vinyl ether-maleic acid copolymer (MVEMA) and polyethyleneimine (PEI) was followed by measurements of turbidity and conductance. The composition of the complex depended on pH of medium. At pH 4.7, the complexation proceeded in 1: 1 stoichiometry over the range of PEI molecular weight 600 to 1900.
