A resin molded article which is a molded article obtained by irradiating a resin molded article containing 100 to 60 parts by weight of (A) syndiotactic 1,2-polybutadiene having a crystallinity of 5% or more and 0 to 40 parts by weight of (B) another thermoplastic polymer with an electron beam, in which the 50% stress of the molded article after the electron beam irradiation (50% M: M2) is from 1.01 to 2.5 times the 50% stress before the electron beam irradiation (50% M: M1), and the molded article has steam sterilization resistance. The molded article is excellent in flexibility and hardness, excellent in steam sterilization resistance, and useful for medical applications such as an infusion tube, an infusion solution container, a catheter and the like.
一种
树脂模塑制品,它是用电子束辐照含有 100 至 60 份(重量百分比)结晶度为 5%或以上的(A)辛二共聚聚
丁二烯和 0 至 40 份(重量百分比)另一种热塑性聚合物的
树脂模塑制品而得到的模塑制品,其中电子束辐照后模塑制品的 50%应力(50% M:M2)是电子束辐照前 50%应力(50% M:M1)的 1.电子束辐照后模塑品的 50% 应力(50% M:M2)是电子束辐照前 50% 应力(50% M:M1)的 1.01 至 2.5 倍,且模塑品具有耐蒸汽灭菌性。该模塑品具有出色的柔韧性和硬度,耐蒸汽灭菌性出色,可用于输液管、输液容器、导管等医疗应用。
