Radiation stabilization of polymeric material |
| abstract |
An irradiation sterilizable composition comprises a semi-crystalline polymer having incorporated therein a mobilizing amount of a non-crystalline liquid mobilizing additive which increases the free volume of the polymer and also having incorporated therein a sterically hindered amine or its N-oxide, N-hydroxide or N-nitroxide salt, with the amine nitrogen being contained in a carbon-nitrogen-carbon chain which forms part of a non-aromatic heterocyclic ring and wherein each of the two carbon atoms of the said chain is bonded either to two alkyl groups which are the same or different and each have 1 to 12 carbon atoms or to an alicyclic group containing 4 to 9 carbon atoms.n[EP0087294A1] |
