Polycondensate composition stabilised against ionising-radiation induced degradation.

摘要

A thermoplastic molding composition resistant to the degradation induced by ionizing-radiation is disclosed. The composition contains an aromatic polycondensate and an agent which is a compound conforming structurally to formula (I) <CHEM> or which is a member selected from the group consisting of oligocarbonate, polycarbonate, copolycarbonate, polyestercarbonate and polyesters which contain structural units conforming to formula (Ia) <CHEM> wherein R<1> to R<1><0> and X are defined. The composition is suitable for the manufacture of shaped articles, especially articles useful in medical applications.
