Vegetable oils: a source of polyols for polyurethane materials

Abstract : This manuscript is dedicated to the literature on vegetable oil-based polyurethanes via the isocyanate/alcohol route. A lot of efforts have been made to replace petroleum-based resources. Among renewable resources, vegetable oils present various advantages going from their availability to the large range of possible chemical modifications they permit. Firstly, the vegetable oil chemical composition and the main commercially available vegetable oil precursors are exposed. Concerning vegetable oils-based polyurethanes, research groups first focused on cross-linked systems directly from triglycerides then on thermoplastic ones from fatty acids or fatty acid methyl esters. This manuscript focuses on thermoplastic PUs and underlines the literature about the introduction of hydroxyl groups and isocyanate functions onto triglycerides and fatty acid derivatives. Besides, in a view to the isocyanate/alcohol approach, vegetable oil-based thermoplastic PUs and corresponding diols and diisocyanates are described in details.
