Patent number: 6870024Abstract: The invention relates to a polymeric urea-urethane obtainable by first reacting a diisocyanate with a polyol to form a doubly NCO-terminated urethane prepolymer. Further reaction is subsequently carried out with a mixture of a primary monoamine and a primary diamine.
