PROCESS AND COMPOSITION FOR THE PRODUCTION OF POLYURETHANE ELASTOMER MOLDINGS ABSTRACT OF THE DISCLOSURE The present invention is directed to a process for the production of polyurethane elastomer moldings by reacting a reaction mixture in a closed mold, wherein said reaction mixture comprises: (a) an organic polyisocyanate; (b) an organic active hydrogen group-containing compound having a molecular weight of from 1800 to 12,000 and containing at least two active hydrogen groups; (c) 1,3,5-triethyl-2,6-diamino benzene and, optionally (d) a catalyst for the reaction between hydroxyl groups and isocyanate groups, wherein component (c) is present in an amount of from 25 to 35 percent by weight based on the combined weight of components (b) and (c), wherein the amounts of components (a), (b) and (c) are such that the isocyanate index of the reaction mixture is from about 90 to 110, and wherein all of said components are processed via a one-shot process whereby (a) is mixed simultaneously either with (b), (c) and (d) or with a non-reacted premixture of some or all of (b), (c) and (d).
