<p>PURPOSE:To obtain base material for a medical vessel having transparency and softness in combination by using a polymer compsn. of an ethylene copolymer and a polybutene amorphous polymer, and a crystalline polypropylene(PP). CONSTITUTION:The base material adequate for the medical vessel is formed by using the polymer compsn. of (A) the ethylene-vinylacetate copolymer, ethylene-acrylate copolymer or ethylene-methacrylate copolymer and (B) the polybutene amorphous polymer. The polymer compsn. consisting of (A) and (B) and (C) the crystalline PP polymer is otherwise used as a forming layer. The medical vessel refers to a vessel and tube for preserving or transporting the blood, medical liquid medicine, etc., and is produced by extruding the polymer compsn. described above via a T die or circular die and molding the resulted flat or tubular sheet or parison to a prescribed shape.</p> |
