    摘要: A sealant for separation of a sample of blood into serum or plasma and clot portions, which has a specific gravity of about 1.03 to 1.08 and a viscosity of about 5,000 to 1,000,000 cps at a shearing speed of 1 second.sup.-1 when measured at 25.degree. C. and comprises as the essential component a polymer essentially consisting of the units of at least one of alkyl acrylates and alkyl methacrylates, and which forms a separator between the serum or plasma portion as the upper layer and the clot portion as the lower layer formed as the result of centrifugation of the blood sample so that the serum or plasma portion is readily separated from the clot portion by decantation.
