RESIN MOLDING AND WORKED ITEM THEREFROM

Document Type and Number:

WIPO Patent Application WO/2004/085523

Kind Code:

A1

Abstract:

A resin molding obtained by exposing to electron beams a resin molding composition comprising 100 to 60 parts by mass of syndiotactic 1,2-polybutadiene of 5% or higher crystallization degree (A) and 0 to 40 parts by mass of other thermoplastic polymer (B). The 50% stress of resin molding after exposure to electron beams (50%M:M2) is in the range of 1.01 to 2.5 times the 50% stress before exposure to electron beams (50%M:M1), and the resin molding is resistant to steam sterilization. The resin molding excels in not only flexibility and hardness but also resistance to steam sterilization, and thus is suitable for medical uses such as an infusion tube, an infusion container, a catheter, etc.
