✦ Synopsis

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 Tg of the polyurethane. Swelling studies reveal that water uptake is high for ionomers. From the tensile data we observe that Zn+' neutralized ionomers showed enhanced properties.

Polyurethanes of different compositions were synthesized by chain extending the prepolymer formed by the reaction of various polyols and diisocyanate with 3,4-dihydroxycinnamic acid. The polyurethanes were converted to their anionomers by treating with metal acetates. The polyurethanes were characte
