Abstract
An anthraquinone monomer, 1,4-bis-(β)-iodopropionyloxy)-9,10-anthraquinone was obtained by the condensation of 1,4-dihydroxy-9,10-anthraquinone with β-chloropropionyl-chloride, followed by an exchange reaction with potassium iodide in the presence of acetone. This derivative was used to synthesize polyetherurethane cationomers by two-step Menschutkin reaction. The resulting ionenes had ammonium quaternary groups content between 98.8 and 149.6 meq/100 g polymer and the quantity of anthraquinone units in polymeric chains was between 29.8 and 45.2 wt.% polymer, respectively. The tensile and thermal properties are similar to other elastomeric polyurethanes.These anthraquinone polyurethane colorants could be useful for coloring a wide variety of products such as fibers, films, coatings, paints or inks.
