A series of novel rosin‐based water‐borne polyurethanes (RWPUs) was prepared from fumaropimaric acid polyester polyol (FAPP) synthesised from rosin acid. Emulsions of the prepared RWPUs were investigated by transmission electron microscopy, and dried films of the emulsions were characterised by Fourier transform infrared spectroscopy, thermogravimetric analysis, X‐ray diffraction and differential scanning calorimetry. Other properties including water absorption, tensile strength, elongation at break, and antibacterial activity of the RWPUs were also determined. The results suggest that RWPU prepared with 35 wt% FAPP has good potential for applications, with improved mechanical properties, thermal stability and water resistance. The RWPU showed excellent antimicrobial properties in killing both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus . Copyright © 2011 Society of Chemical Industry
