    • A poly(urethane-urea) comprising segments derived from (a) a diisocyanate or mixture of diisocyanates; (b) a polyether polyol comprising repeating units of general formula —[(CH2)mO]— wherein each m is the same or different and is 3 or 4, or a mixture of said polyether polyols; and (c) a diamine or mixture of diamines, wherein said polyether polyol segment(s) (b) make up at least 70% by weight of the dry poly(urethane-urea) and wherein the ether oxygen atoms of said polyether polyol segment(s) (b) make up at least 15% by weight of the dry poly(urethane-urea); and wherein said poly(urethane-urea) has an amine end group content of up to 0.2% by weight. These poly(urethane-urea)s can be manufactured and compounded to give one-component and two-component coating formulations, which can be used to produce materials with good barrier properties such as waterproof breathable fabrics, foul weather and protective clothing, and films for medical and other applications.
