| abstract |
The present invention relates to a process for the preparation of polvols of formula (I ") R 'representing H or an alkyl group, R" representing in particular an alkyl group, A representing an alkylene radical and R representing in particular a group -A -O-Y Wherein A is an alkylene radical and Y 'is in particular H, said process comprising in particular a step of epoxidation of a compound of formula R "representing H or an alkyl group, A being as defined above in the formula ( I ") and R representing in particular a group -A -OY ', A being as defined above in formula (I") and Y' representing in particular H, to obtain a compound of formula A being as defined hereinabove. above, R "'representing H or an alkyl group and R representing in particular a group of formula -A -OY', A being as defined above in formula (I") and Y 'representing in particular H. |
