Graft polycarbonates, their preparation and their use as moldings

Claim 1

A process for the production of soluble thermoplastic graft polycarbonate with a molecular weight (weight average Mw) of about 30,000 to 400,000, in which an aromatic polycarbonate with on average at least one unsaturated end group per polycarbonate molecule, having the formula II ##STR6## in which Z=a radical of a diphenol, n=an integer from 30 to 100, and E represents a saturated end group of the formula IIIb or an unsaturated end group of the formula IIIa ##STR7## in which for IIIa, m denotes zero and R denotes ##STR8## and in which for IIIb, m is zero and R is C 1 -C 18 -alkyl or m is 1 and R is H, alkyl or halogen, is polymerized by means of solution polymerization in the presence of monomers which can be polymerized under free radical conditions, selected from vinyl monomers and acrylic monomers, during which the weight ratio of the starting polycarbonate to the monomers which can be polymerized under free radical conditions is about 70:30 to 10:90, and during which the concentration of the reaction solution does not exceed about 30% by weight, relative to the total weight of polycarbonate with unsaturated end groups, monomers which can be polymerized under free radical conditions and reaction medium.
