The a.c. conductance of partially neutralized fractions of polyacrylic and polymethacrylic acids has been investigated in salt‐free solutions. Experimental variables included frequency (10 to 50,000 cycles), nature of counterions (potassium, sodium, and lithium), molecular weight, degree of ionization, concentration, and temperature. The use of a polarization compensated twin cell arrangement in frequency dispersion measurements is described.
