Polymeric solid ionic conductor is a new class in functional materials. Its study has grown vigorously in recent years. The polymerization of polyacrylic acid–alkali metal salt complex is studied for the first time. Some important factors and reaction conditions, such as polymerization temperature, concentration of initiator and amount of alkali metal salt, have been discussed. The results, show that the polymerization temperature should be controlled at about 60°C and the best initiator's amount is 0.04–0.05% of the whole weight of materials. The complex has been characterized with infrared spectroscopy, differential scanning calorimetry, conductance ratio and adhesion strength determinations, acute toxicity and skin allergy reaction. This complex is a kind of multifunctional medical conductive adhesive with good performances in medicine, conductive adhesiveness and pressure sensitivity. Copyright © 1999 John Wiley & Sons, Ltd.
