Abstract
The disclosure relates to water-dispersible polyurethane polymers as well as related polyurethane dispersion (PUD) compositions including the same, methods of making the same, methods of using the same, and articles coated with the same. The water-dispersible polyurethane polymer includes hydrophobic oligomeric polyether soft segments that include 1,2-di-substituted oxyethylene repeating units. The 1,2-disubstituted oxyethylene repeating units are derived from unsaturated fatty acid esters, such as from a distribution of epoxidized vegetable oil fatty acid esters subjected to a ring-opening polymerization process for oligomeric polyether polyol formation. The water-dispersible polyurethane polymer further includes hard segments common to other PUD compositions.
