Abstract
Various disperse dyes based on m-phenylenediamine have been prepared. These dyes were then polycondensed with Toluene 2, 4-diisocyanate. The resultant colored polyureas were characterized by elements analyses, IR spectral studies, estimation by monaqueous conductometric titration and thermogravimetry. All the polyureas were subjected to electrical conductivity determination at room temperature.
