Synthesis and characterization of low crystalline waterborne polyurethane for potential application in water-based ink binder

- The new synthesis process combines prepolymer isocyanate with acetone process.
- Nanoparticles with no conglomeration and a good stability were obtained easily.
- The polyurethane has low crystallinity and good thermal resistance.
- The polyurethane with good performance could be used as water-based ink binder.
