Page/Page column 18, (2013/02/28)
The present invention relates to a method for preparing polyols of formula (I″) R′1 being H or an alkyl group, R″ being especially an alkyl group, A1, being an alkylene radical and R3, are being especially a group -A2-O—Y′, A2 being an alkylene radical and Y′ being especially H, said method especially comprising a step of epoxidation of a compound of formula R″1 being H or an alkyl group, A1 being defined as above in formula (I″) and R4 being especially a group -A2-O—Y1′, A2 being defined as above in formula (I″) and Y′1 being especially H, in order to obtain a compound of formula A1 being defined as above, R′″1 being H or an alkyl group and R5 being especially a group of formula -A2-O—Y2′, A2 being as defined above in formula (I″) and Y′2 being especially H,
