摘要： The present invention provides a chlorinated polyvinyl chloride resin that has resistance to thermal decomposition, provides excellent continuous productivity in molding, and imparts both processability and unevenness-preventing properties to a molded article. The present invention relates to a chlorinated polyvinyl chloride resin, containing three components including a A150 component, a B150 component, and a C150 component, and having a percentage of the C150 component (C150 component/(A150 component+B150 component+C150 component)) of less than 8.0%, the three components being identified by measuring the chlorinated polyvinyl chloride resin by a solid echo method using pulse NMR at 150° C. to give a free induction decay curve of 1H spin-spin relaxation, and subjecting the free induction decay curve to waveform separation into three curves derived from the A150 component, the B150 component, and the C150 component in order of shorter relaxation time using the least square method.

A blood collection container according to the present invention is a blood collection container into which a predetermined amount of blood is collected. The blood collection container includes a blood collection container main body, and a blood plasma separation material, an osmotic pressure regulator, and an anticoagulant contained in the blood collection container main body. The specific gravity of the blood plasma separation material at 25° C. is 1.030 or more and 1.120 or less. When the osmotic pressure regulator and the anticoagulant contained in the blood collection container main body are dissolved in an amount of physiological saline solution equivalent to a predetermined amount of blood collected in the blood collection container to obtain an osmotic pressure measurement solution, the specific gravity of the blood plasma separation material at 25° C. and the osmotic pressure of the osmotic pressure measurement solution satisfy a specific relationship.
