Synthesis and characterization of novel colored polyureas

الملخص EN

Various disperse dyes based on m-phenylenediamine have been prepared.

These dyes then polycondense with hex methylene diisocyanate.

The resultant colored polyurias were characterized by N content, IR spectral studies, Mgn estimation by no aqueous conduct metric titration and thermogravimetry.

All the polyuria was subjected to electrical conductivity measurement at room temperature.
