An improved thermoplastic molding composition containing polycarbonate and a polyester copolymer based on cyclohexanedimethanol, ethylene glycol and phthalic acid is disclosed. Improved thermal stability and resistance to gamma-radiation results from the incorporation of a phosphite conforming to <IMG> where n, m, p and r are integers, and where R is H, an alkyl or an aryl group and R3 denotes an alkyl or aryl group.
