UNA COMPOSICION DE TOLUENODIAMINA

摘要

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: 1 2 3 wherein R1, R2 and R3 are C1-3 alkyl groups or R2 and R3 are combined to form a C5-6 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.
