Provided are a polymer for preparing an ion conductive polymer electrolyte, and an ion conductive polymer electrolyte using the polymer which is high in dielectric constant and is excellent in the solubility to an ion conductive salt and mechanical stability. The polymer is represented by the formula 1 and is formed by grafting polyaniline or a polyaniline derivative to a thermoplastic polyurethane and polyurethane derivative polymer matrix, wherein R1, R2, R3 and R4 are H, SO3-, -SO3H, R7S3-, -R7SO3H, -OCH3, -CH3, C2H5-, -F, -Cl, -Br, -I, -NR72, -NHCOR7, -OH, -O-, -SR7, -OR7, -OCOR7, -NO2, -COOH, -COOR7-, -COR7, -CHO or -CN; R7 is a C1-C8 alkyl group, an aryl group or an aralkyl group; the fraction of a ring containing at least one of R1, R2, R3 or R4 represented by SO3-, -SO3H, -R7SO3 or -R7SO3H is 20-100 %; TPU is a polyurethane represented by the formula 2; and n is an integer of 1-1,000. In the formula 2, I is a C1-C32 alicyclic, aliphatic or aromatic isocyanate unit; P is a polyol unit; R1 and R2 are an alkyl group; and n is an integer of 1-1,000.
