Abstract

Polyurethane anionomers based on phenolphthalins have been characterized by differential scanning calorimetry, swelling, and mechanical studies. DSC study shows that introduction of ionic groups into the polymer chain lowers the T_g of the polyurethane. Swelling studies reveal that water uptake is high for ionomers. From the tensile data we observe that Zn⁺² neutralized ionomers showed enhanced properties. ©1996 John Wiley & Sons, Inc.
