摘要： A polyester is provided which facilitates the separation of blood into light and heavy phases via centrifugation in a blood collection vessel. The polyester is useful as a component of a partitioning composition formulated to have appropriate specific gravity to be positioned intermediate the light and heavy blood phases during centrifugation. The polyester composition can be prepared with relative ease compared to prior art polyesters useful in blood partitioning compositions. The polyesters of this invention comprise a dicarboxylic acid member, a polymeric fatty acid, a diol member and a moiety having at least one polymerizable carbon-carbon double bond and at least one functional group capable of reacting with the ends of the polyester chain. The polyesters have a lower viscosity when synthesized and are later cured to increase their viscosity to the desired level.
