Beschreibung
Zusammenfassung:	A method for forming a polyurea-containing urethane elastomer comprising reacting together a polyol comprised of an OH terminated polyether, an organic polyisocyanate and water in amounts sufficient to produce carbon dioxide and form a polyurethane elastomer containing polyurea, in the presence of at least 10 volume percent oil, and curing to form said elastomer under conditions whereby said carbon dioxide is dissolved in said elastomer to produce a substantially void-free elastomer.
