Vegetable oils have been a frequently spotted in this search becausethey are versatile, highly available and a low cost liquid biosource, which canbe used in the synthesis of a wide plethora of different polymers and reactivemonomers. Following the same idea of reducing the environmental stress, thetraditional polyurethanes that are soluble in organic solvents have beentargeted for replacement, particularly in applications such as adhesives andcoatings, in which the solvent is released to the atmosphere increasing the airpollution. Instead, waterborne polyurethanes (WBPU), which are polyurethanedispersions (PUD) prepared in aqueous media, release benign water to theatmosphere during use as supported or self-standing films for differentapplications. In this brief review, the contributions to the development ofWBPUs based on vegetable oils are discussed, focusing mainly on thecontributions of the last decade. The synthesis of ionic and nonionic PUDs,their characterization and the properties of the resulting dried materials, aswell as derived composite materials are considered. Keywords: Vegetable oils; polyurethane dispersions (PUD);waterborne polyurethane (WBPU); biopolyols; biopolyurethanes; coatings;adhesives; ink binders<!-- /* Font Definitions */ @font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;mso-font-charset:0;mso-generic-font-family:swiss;mso-font-pitch:variable;mso-font-signature:-536859905 -1073732485 9 0 511 0;}@font-face{font-family:Times;panose-1:2 0 5 0 0 0 0 0 0 0;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:3 0 0 0 7 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin:0cm;margin-bottom:.0001pt;mso-pagination:widow-orphan;font-size:12.0pt;font-family:Times;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:minor-bidi;}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-family:Times;mso-ascii-font-family:Times;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-hansi-font-family:Times;mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:minor-bidi;}size:595.0pt 842.0pt;margin:72.0pt 72.0pt 72.0pt 72.0pt;mso-header-margin:35.45pt;mso-footer-margin:35.45pt;mso-paper-source:0;}div.WordSection1{page:WordSection1;}<!-- /* Font Definitions */ @font-face{font-family:Courier;panose-1:2 0 5 0 0 0 0 0 0 0;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:3 0 0 0 3 0;}@font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:Times;panose-1:2 0 5 0 0 0 0 0 0 0;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:3 0 0 0 7 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin:0cm;margin-bottom:.0001pt;mso-pagination:widow-orphan;font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-font-family:"Times New Roman";}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-size:10.0pt;mso-ansi-font-size:10.0pt;mso-bidi-font-size:10.0pt;font-family:Courier;mso-ascii-font-family:Courier;mso-fareast-font-family:Courier;mso-hansi-font-family:Courier;}size:612.0pt 792.0pt;margin:72.0pt 72.0pt 72.0pt 72.0pt;mso-header-margin:36.0pt;mso-footer-margin:36.0pt;mso-paper-source:0;}div.WordSection1{page:WordSection1;}mso-level-number-format:roman-lower;mso-level-tab-stop:324.0pt;mso-level-number-position:right;text-indent:-9.0pt;}ol{margin-bottom:0cm;}ul{margin-bottom:0cm;}
