Abstract

The disclosure covers diamino-s-triazines which are useful in polymer synthesis, such as polyimides. Also covered are dinitros-triazines which can be used as intermediates for the diamino compounds. The diamines are prepared by a condensation of 2substituted-4,6-dichlorotriazines with diamines or with nitroamines. The product from the latter reaction can be reduced subsequently to diamines.
