Aqueous polyurethane (APU) dispersions with improved hydrophilicity were presented and characterized. In order to make APU products more competitive, anionic diols and dimethylopropanic acid (DMPA) were introduced into the macromoleculars of APU. The particle sizes of the APU dispersions have been reduced from 0.7~3μm to 0.05~0.6μm, and the storage stability has been prolonged from 6 months to 12 months. It is efficient to prepare the self-emulsifiable APU dispersions by applying anionic polyester diols and using triethanolamine (TEOA) as a neutralization agent.
