Abstract

L'invention concerne l'industrie des polymères. Elle a pour objet des copolyesters issus d'acides dibasiques mixtes et d'un diol ramifié et plus particulièrement d'un mélange d'un acide dicarboxylique aliphatique saturé de 4 à 12 atomes de carbone, d'un acide gras polymère contenant au moins 75 % en poids d'acide dibasique en C36 et d'un ou plusieurs diols ramifiés éventuellement en mélange avec une quantité mineure de diol non ramifié. Ces copolyesters sont préférés en raison de l'équilibre remarquable de leurs propriétés physiques et chimiques comme agents formant barrière à utiliser en petites quantités dans des tubes de fractionnement du sang pour séparer efficacement la phase légère et la phase lourde sang après centrifugation.
