The synthesis is described of some aromatic polyamides based on unsubstituted, and methyl-, carboxy-, and sulfo-substituted diamines by interfacial polycondensation. Some of them are crosslinked and some of them contain heterocyclic aromatic rings. Their chemical structures are characterized by IR a
## Abstract In the present work, a series of aromatic/aliphatic co‐polyureas have been synthesized from 4,4‐diphenylmethane diisocyanate (MDI), __m__‐phenylene diamine (__m__‐PDA), and 1,6‐diaminohexane (HDA) in DMAc by a two‐stage solution polymerization route. Characterizations of the polyurea pr
