Beschreibung
Zusammenfassung:	Poliéster poliol de la fórmula general Rx-Ry-Z-Ry'-Rx', en donde: - Z es un alcohol de azúcar C3 a C8, - Ry y Ry' son diésteres de la fórmula -OOC-Cn-COO- con n comprendida entre 2 y 34, y - Rx y Rx' son monoalcoholes C2 a C12 idénticos o diferentes. 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′.
