The aim of the study was to determine the structure and electric properties of new solid polyurethane electrolytes. Polyurethane samples were prepared from 4,4'-diphenylmethane diisocyanate (MDI), poly(tctramethylene glycol) (PTMG) and 1,4-butanediol (BDO). Doping salts, LiCl or LiClOj were introduced into the polyurethane melt during extrusion using a laboratory twin-extruder. The obtained solid polyurethane electrolyte samples were characterized by FTIR-ATR spectroscopy and strength-strain properties. The conductivity was estimated by means of impedance spectroscopy using the direct current (DC) method and alternating current (AC) method. The conductivity was found to be related to the mode of sample preparation, namely, to doping in the liquid state at 60°C during polyurethane synthesis or mixing at 200"C in the melt.
