Abstract
Abstract A poly(urethane)ureamide which comprises a polymer obtained by a reaction of (a) a polyether derivative of the general formula [I] and (b) a polyisocyanate exhibits an excellent wear resistance and heat resistance due to the presence of the aromatic amido groups ##STR1## wherein A is an n-valent radical obtained by removal of hydroxyl groups from an n-valent polyoxyalkylenepolyol having a molecular weight of 400 to 10,000, n is an integer of 2 to 8, x is an average value and a number of 0≦x<(n-1) and y is an average value and a number of 0.05≦y<1.
