ABSTRACT:
This invention relates to a class of tertiary-alkyltoluenediamines having alkyl groups ortho to an amine group. More particularly the aromatic diamines are represented by the formulas: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are C.sub.1-3 alkyl groups or R.sub.2 and R.sub.3 are combined to form a C.sub.5-6 membered ring.
The above described alkylated aromatic diamines have been found to be well suited for use as a chain extender in forming polyurethane/urea elastomer systems and the mono tert-butyltoluenediamine isomers have been found to be nonmutagenic in the Ames test.
