| abstract |
A thermoplastic elastomer composition comprising: (A) 85-98 wt % of syndiotactic 1,2-polybutadiene having a 1,2-bond content of 70% or more and a degree of crystallinity of 5-50% and (B) 2-15 wt % of a styrene-butadiene-styrene block copolymer and/or styrene-isoprene-styrene block copolymer is disclosed. Since the thermoplastic elastomer composition and a molded article made from the composition can be firmly bonded with a polar resin using an organic solvent, the composition is useful as a material of components used for medical treatment such as an infusion set for medical treatment. |
