The novel synthesis of novel Ionic Liquid Crystal Polyurethanes (ILCPUs) (main-chain liquid crystals with the ionic group as a side group) was successfully demonstrated. Sulfonic acids were used as negative group and sodium ions as a positive charge. All the synthesized compounds show low molecular weight ILCPUs and exhibit nematic phase is a very rare mesophase for ionic liquid crystals. The melt compatibilization of Thermoplastic Polyurethane (TPU) and Styrene-Acrylonitrile (SAN) blends by Ionic Liquid Crystalline Polyurethanes (ILCPUs) were prepared using a two-roll mill at 220-235 °C. The results obtained from the various analyses suggest that ILCPUs could be used as an effective compatibilizer for the immiscible polymers blends.
