The effects of the molecular weight and structure of polycarbonatediols on the properties of waterborne polyurethanes

- Waterborne polyurethanes are synthesized from 4 different polycarbonatediols.
- WPUs show different properties as molecular weight and structure of PCDL varies.
- The emulsions with nanoparticles display excellent stability.
- Polyurethanes have much better properties as molecular weight of PCDL increases.
- Homopolymer-based polyurethanes have superior thermal and mechanical properties.
