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&#x2032; 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.

Method for producing polyester polyols and use thereof in polyurethane

A rigid foam or a composition allowing a rigid foam to be obtained, including a polyester polyol or a polymer including a polyester polyol, the polyester polyol being obtained by a first polycondensation (a) of a C3 to C8 sugar alcohol Z and two identical or different C4 to C36 diacids Y and Y' and a second polycondensation (b) of the product obtained in (a) with two identical or different C2 to C12 diols X and X&#x2032;.
