Beschreibung
Zusammenfassung:	The present invention relates to a polyureaurethane wherein the prepolymer comprising said polyureaurethane has a NCO to OH equivalent ratio of from 2.0 to less than 2.5. In an embodiment, the polyureaurethane prepolymer comprises a polyisocyanate and at least one OH-containing material, which can be reacted with an amine-containing curing agent to produce the polyureaurethane of the present invention.
