Abstract
Copolyesters are provided which are derived from mixed dibasic acids and a branched-chain diol. These copolyesters possess a unique balance of physical and chemical characteristics which permits their use in small amounts in blood separation tubes to provide an effective barrier between the light and heavy phases of the blood after centrifuging.
