ABSTRACT OF THE DISCLOSURE Disclosed is a class of poly(aminoaromatic) compounds (I) obtained by capping polymeric polyols or polythiols with aromatic amine groups wherein the latter groups are linked by -O- or -S- to the polyol (polythiol) residues. Also disclosed are the precursor poly(nitro- aromatic) compounds (II) and process therefor from which the compounds (I) are derived. The polyamines are characterized by amine reactiv- ities in respect of isocyanate polyaddition reactions which allows for polymer reaction rates that are intermediate of prior art related polyamine compounds. Accordingly, the compounds (I) find their prime utility in the formation of synthetic resins containing polyurea linkages.
