Polyolefin articles, especially polypropylene hypodermic syringes are made more resistant to the yellow discolouration and embrittlement which accompanies sterilisation by gamma-irradiation by the addition to the polyolefin of a heterocyclic hindered amine, e.g. di-(2,2,6,6-tetra- methyl-4-piperidyl)sebacate, to the amount from 0.01 to 2% by weight of the polymer.
在聚烯烃中加入杂环受阻胺,如二(2,2,6,6-四甲基-4-哌啶基)癸二酸酯,使聚烯烃制品,特别是聚丙烯皮下注射器,更耐受伽马射线辐照灭菌时产生的黄色褪色和脆化,其用量为聚合物重量的 0.01 至 2%。
