Abstract
The present invention relates to the use of a compound of formula (I): wherein: R represents a linear or branched alkyl group, comprising from 3 to 27 carbon atoms, said alkyl group being substituted with at least two hydroxyl groups, and which may optionally contain one or more unsaturations; and R′ is selected from sugars or sugar-alcohols; for preparing polyurethanes and polyesters.
Claims17
The use of a compound of formula (I):
- wherein:
- R represents a linear or branched alkyl group, comprising from 3 to 27 carbon atoms, preferably from 8 to 27 carbon atoms, said alkyl group being substituted with at least two hydroxyl groups, and may optionally contain one or more unsaturations;
- and
- R′ is selected from sugars or sugar-alcohols;
- for preparing polymers selected from polyurethanes and polyesters.
A compound of formula (I):
