The interaction between dodecyl benzene sulfonic acid (DBSA) with poly (ethylene oxide) (PEO) has been investigated at 293 K by conductance and surface tension measurements. The effect of concentration on the electrical conductance of DBSA in solution itself from 293-323 K above and below the Critical Micelle Concentration (CMC) was also studied. A number of important parameters i.e. critical aggregation concentration (CAC), Gibb’s free energy (DG) and binding ratio (R) was also determined. The effect of NaCl on the CAC and Polymer saturation point (PSP) was also investigated. It was found that conductance of PEO increased with the introduction of DBSA
