Abstract

A thermoplastic molding composition is disclosed. The composition that contains at least one member selected from the group consisting of aromatic polycarbonate and polyester carbonate, a rubber-modified vinyl (co)polymer, and calcium carbonate having average particle diameter of less than 100 nm is particularly suitable for making articles resistant to hydrolysis.
