A polyester polyol of formula produced by a first polycondensation (a) of a sugar alcohol Z in C3 to C8 and two diacids Y and Y′ which are the same or different in C4 to C36, and a second polycondensation (b) of the product produced in (a) with two diols X and X′ which are the same or different in C2 to C12, the polymer including such a polyester polyol. Also, a method for producing the polyester polyols and the use thereof in foams, adhesives, coatings or elastomers of polyurethane or polyisocyanurate.
