Abstract

Moulding compositions of polycarbonate, polyalkylene terephthalate and, optionally, polymer having a glass transition temperature below -20.degree. C. may be processed to form particularly low-distortion mouldings when the polycarbonate consists at least partly of o,o,o',o'-tetramethyl-besphenol-polycarbonate.
