MOULDING COMPOSITIONS FROM MIXTURES OF POLYCARBONATES HAVING A HIGHER DISPERSED SOLUBILITY

摘要

This invention relates to halogen-free binary mixtures of two fully aromatic polycarbonates each having a disperse solubility of from 18 to 35 (J/ccm)1/2, in which both polycarbonates are of high molecular weight and each contains not more than 70 mol-% of bisphenol A. The invention further relates to the use of these mixtures for optical data stores and to moulded parts produced from the mixtures.
