Polyols are prepared from unsaturated vegetable oils by introducing hydroxyl groups at the position of double bonds (Narine et al., 2007). Hydroxyl groups can be introduced in many ways, resultingin different polyol structures, which when converted to polyurethane (PU), impart different properties to the final product (Lin et al., 2007). Primary hydroxyl groups in polyols are desirable as they undergo rapid polymerisation processes and their compositions greatly influence the physical properties of the polymeric articles (Narayan et al., 2006).
