(57) [Abstract] [Purpose] It has excellent flexibility and kink resistance, has high-pressure steam sterilization resistance, and is heat-weld to other tubes that do not generate toxic gas when incinerated. Provide a medical multilayer tube excellent in solvent adhesion. SOLUTION: This is obtained by hydrogenating a polypropylene resin (a), a block copolymer consisting of one or more polymer blocks composed of vinyl aromatic and one or more polymer blocks composed of isoprene and / or butadiene. A resin composition comprising a hydrogenated block copolymer and at least one copolymer (b) selected from the group consisting of a hydrogenated copolymer obtained by hydrogenating a vinyl aromatic compound and a butadiene copolymer At least a base layer A and an adhesive layer B composed of And a multilayer tube composed of two layers. |
