Improved radiation sterilizable compositions and articles can be produced without the use of non-crystalline mobilizing additives, such as mineral oil, if a low crystallinity polymer composition includes a stabilizer system comprising of a hindered phenolic antioxidant and a thioether and/or thioester and the polymer is selected and to have a melt flow initially is below about 5 and finally in the range of from about 12.0 to about 50.
如果低结晶度聚合物组合物中包含由受阻
酚类抗氧化剂和
硫醚和/或
硫酯组成的稳定剂系统,并且聚合物经过选择,熔体流动性最初低于约 5,最终在约 12.0 至约 50 的范围内,则可以在不使用矿物油等非结晶动员添加剂的情况下生产出改进的可辐射灭菌组合物和物品。
