Abstract Sodium sulfosuccinate coupled poly(ethylene glycol) (PEG) (S–PEG–SS) conductive polymers for hot melt adhesives are synthesized from PEG, maleic anhydride, and sodium hydrogen sulphite using a one-pot three-step reaction. Infrared spectroscopy and 1H NMR spectroscopy are used to characterize the molecular structure and to determine the yield of esterification. S–PEG150–SS has the highest yield of esterification, whereas S–PEG2000–SS provides the lowest yield of esterification. Gel permeation chromatography and shear viscosity measurements are applied to characterize multiple condensation products and to describe the viscoelastic properties. The results reveal that the viscoelastic properties and the conductivity depend on molar mass of esterified PEG, on the degree of condensation, and on the concentration of ions.
