Zusammenfassung:	In one aspect, a polyester polyol, includes a condensation product of a biobased C7-C12 dicarboxylic acid, a biobased C2-C10 diol, and a branched diol having a formula of (I) where R1 and R2 are independently a linear alkylene linkage having 1 to 3 carbon atoms, and R3 and R4 are independently an alkyl group having 1 to 3 carbon atoms, and wherein the weight ratio of the biobased C2-C10 diol to the branched diol is (25-53) to (47- 75). Also provided is a polyurethane system comprising the polyester polyol and a process of preparing the polyester polyol. Selon un aspect, un polyester polyol comprend un produit de condensation d'un acide dicarboxylique en C7-C12 biosourcé, un diol en C2-C10 biosourcé et un diol ramifié de formule (I), dans laquelle R1 et R2 sont indépendamment une liaison alkylène linéaire ayant de 1 à 3 atomes de carbone, et R3 et R4 sont indépendamment un groupe alkyle ayant de 1 à 3 atomes de carbone, et le rapport pondéral du diol en C2-C10 biosourcé au diol ramifié étant compris entre (25-53) et (47-75). L'invention concerne également un système de polyuréthane comprenant le polyester polyol et un procédé de préparation du polyester polyol.
