<P>PROBLEM TO BE SOLVED: To provide a resin composition for a dialyzer body for dialysis and a header, which is resistant to electron beams and γ rays, is excellent in the balance of transparency, impact resistance and rigidity, and is also excellent in machinability, the dialyzer body for dialysis, and the header. <P>SOLUTION: The resin composition includes the linear block copolymer (a) of vinyl aromatic hydrocarbon and conjugated diene, and the straight chain block copolymer (b) of the vinyl aromatic hydrocarbon and the conjugated diene, and a weight ratio (a)/(b) is 80/20 to 20/80. The (a) comprises a conjugated diene polymer block (B), a vinyl aromatic hydrocarbon polymer block (S) and a copolymer block (B/S), and respective ratios are numerically stipulated. The (a) has at least one peak molecular weight in the range of 50,000-150,000 and at least one peak molecular weight in the range of 150,000-350,000, and the (S) has at least one peak molecular weight in the range of 10,000-60,000 and at least one peak molecular weight in the range of 120,000-250,000. <P>COPYRIGHT: (C)2011,JPO&INPIT |
