摘要：

Epoxidized linseed oil (ELO) was used as a raw material to obtain polyols for possible polymer applications. Two types of polyols have been synthesized through oxirane ring opening with water under both acidic and alkaline media, on one hand, and with allylmagnesium bromide, on the other hand. The ring opening via Grignard derivatives allowed the simultaneous grafting of unsaturated allyl moieties onto the triglyceride backbone, thus leading to a polyunsaturated branched polyol. FT-IR and 1H-NMR spectra confirmed the structure of the obtained products.
