Abstract
<p>Recently, bio-based polyurethanes have received much attention as environmentally benign materials. This study deals with a dimer acid-containing polyurethane ionomer showing good elastic properties. A polyester polyol was prepared by the reaction of dimer acid with an excess of 1,4-butanediol. The polyol was reacted with 4,4’-diphenylmethanediisocyanate and N-methyldiethanolamine, and subsequently, the reaction of the resulting polyurethane with 1,3-propanesultone produced the polyurethane ionomer possessing the zwitterionic group. The FT-IR and DSC data suggest the aggregation of the zwitterionic group in the polyurethane. Mechanical properties were improved by the introduction of the zwitterionic group.</p>
