ABSTRACT:
This invention provides chain extender compositions. These compositions comprise(i) an aliphatic secondary diamine, and(ii) a component selected from the group consisting of:(a) a cycloaliphatic primary diamine;(b) an aliphatic secondary diamine;(c) an aliphatic secondary diamine and an aliphatic primary diamine;(d) an aliphatic diimine; and(e) a combination of any two or more of (a) through (d),with the proviso that when (ii) is (a), (i) is a noncyclic aliphatic secondary diamine. Processes for producing polyurethanes, polyureas, and polyurea-urethanes are also provided.
