Claim 0:
1. A polycarbonate composition containing
(i) at least one polysiloxane-polycarbonate block co-condensate,
(ii) at least one siloxane,
(iii) optionally at least one further polymer distinct from component (i) and
(iv) optionally at least one further additive,, wherein the at least one siloxane of component (ii) is represented by general chemical formula (II), general chemical formula (IIa), general chemical formula (III) and/or general chemical formula (IV), in which Z1, Z2 and Z3 each independently of one another represent methyl, ethyl, propyl, butyl, isopropyl, isobutyl, vinyl, propenyl, butenyl, C5 to C18 alkyl, methacryloxypropyl; mono or dicarbinol, methoxy, ethoxy, propoxy, butoxy, epoxypropoxypropyl, optionally alkyl- or alkoxy-substituted phenylethyl, phenylisopropyl, 3-phenylpropyl or phenyl, hydroxy, hydrogen, chlorine, fluorine or CN,
R10 independently at each occurrence represents hydrogen, methyl, ethyl, propyl, butyl, isopropyl, isobutyl, isooctyl, isononyl or isodecyl,
R11 independently at each occurrence represents methyl, ethyl, propyl, butyl, isopropyl, isobutyl, vinyl, propenyl, butenyl, C5 to C18 alkyl, methacryloxypropyl; mono or dicarbinol, methoxy, ethoxy, propoxy, butoxy, epoxypropoxypropyl, optionally alkyl- or alkoxy-substituted phenylethyl, phenylisopropyl, 3-phenylpropyl or phenyl, hydroxy, hydrogen, chlorine, fluorine or CN,
r is a natural number between 0 and 3,
s and t are each independently of one another a natural number between 1 and 250, and
w and v are each independently of one another a natural number between 1 and 250, and
groups having the indices s, w, v, t and u can have a random distribution in the siloxane of component (ii).
