By means of ionizing radiation sterilizable moulded parts made from polycarbonate |
| abstract |
The invention relates to a thermoplastic composition comprising A) aromatic polycarbonate, B) 0.1 to 5 wt.-% one or more polyether polyol(s) and C) one or more thermal stabilizer(s) selected from the group consisting of thio compounds excluding the following component D, characterized in that the composition additionally comprises D) 3,3'-thiodipropionic acid, wherein the total amount of components C plus D is 0.01 to 1.0 wt.-%. The invention also relates to medical technology products or parts of medical technology products consisting of such compositions as well as to a process for sterilization of such moulded parts by means of irradiation. The polycarbonate compositions according to the invention show significantly less yellowing after irradiation than known compositions. |
