A fluid which comprises an olefin-terminated polyester an unmodified polyester and a polymerized. alpha. -olefin is provided which facilitates the separation of blood into light and heavy phases via centrifugation in a blood collection vessel. The fluid 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. A partitioning composition including a fluid of the invention provides a particular advantage in blood collection vessels used in therapeutic drug monitoring, due to the relatively low affinity between the fluid component of the composition and commonly monitored classes of drugs.

Polyesters are described which are substantially the condensation products of at least one dicarboxylic acid, at least one volatile diol and at least one hydroxyl-functional component with functionality greater than 2 which controls ultimate viscosity. The products are suitable vehicles for the formulated thixotropic gels for centrifugal separation of fluids such as serum into high and low density components of, for example, separation of mixtures of cells on the basis of density.

The flow characteristics and rheological properties of high molecular weight thermoplastic polyamides are significantly improved by blending therewith a small amount of a polyamide derived from high molecular weight dibasic acids. In addition to improving the processability of the thermoplastic resin, the blends and manufactured articles produced therefrom have other desirable properties.

Liquid copolyesters useful as plasticizers for vinyl resins are provided. The copolyesters are obtained by the esterification of specific aliphatic dicarboxylic acid ester mixtures with 1,4-butanediol and an aliphatic saturated monofunctional alcohol. The copolyesters have acceptably low solidification points; they are resistant to hydrocarbon extraction; and they impart good low-temperature flexibility to PVC compositions plasticized therewith.

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. A partitioning composition including a polyester of the invention provides a particular advantage in blood collection vessels due to its lighter and more consistent coloration. The polyester composition can be prepared with relative ease compared to prior art polyesters useful in blood partitioning compositions.

Polyester compositions containing organophosphorus derivatives as stabilizers are disclosed. Methods of stabilizing polyesters are also provided by incorporating the organophosphorus derivatives during processing to prevent thermal and catalytic decomposition, and with improvements in resin color, molecular weight retention and mechanical properties. This invention also affords an efficient method of inhibiting the decomposition activity of the first stage catalyst in the production of high polymeric condensation polyester resins.
