Abstract (en)

[origin: US4186154A] The present invention relates to mixtures comprising about 60% by weight to 5% by weight of aromatic polycarbonates which have a Mw between about 60,000 and 120,000 (component A) and about 40% by weight to 95% by weight of aromatic polycarbonates which have a Mw between about 28,000 and 40,000 (component B), as well as to processes for their preparation and their use for the production of shaped articles. The melt which can be prepared from the mixtures according to the invention has a high stability and the films obtainable therefrom have a high resistance towards stress cracking.
