| abstract |
The present disclosure is drawn to a reactive polyurethane dispersion including a polymer strand having a polymer backbone that has two ends terminating at a first capping unit and a second capping unit. The polymer backbone can include polymerized monomers including a reactive diol and a diisocyanate. The reactive diol can be an acrylate-containing diol, a methacrylate-containing diol, an allyl-containing diol, or combination thereof. The first capping unit can be an allyl-containing monoalcohol reacted with an isocyanate group of the diisocyanate. The second capping unit can be an ionic stabilizing group. |
