Abstract
Polyurethane anionomers based on phenolphthalins have been characteriz ed by differential scanning calorimetry, swelling, and mechanical stud ies. DSC study shows that introduction of ionic groups into the polyme r chain lowers the T-g of the polyurethane. Swelling studies reveal th at water uptake is high for ionomers. From the tensile data we observe that Zn+2 neutralized ionomers showed enhanced properties. (C) 1996 J ohn Wiley & Sons, Inc.
