Claim:
1. A process for preparing an impact-modified polymer composition comprising A) from 10 to 98 parts by weight, based on the sum of components A+B+C+D+E, of at least one polymer selected from the group consisting of aromatic polycarbonates, aromatic polyester carbonates and aromatic polyesters, as well as mixtures thereof, B) from 0.5 to 50.0 parts by weight, based on the sum of components A+B+C+D+E, of at least one pulverulent rubber-modified vinyl (co)polymer, C) from 0 to 80 parts by weight, based on the sum of components A+B+C+D+E, of at least one component selected from the group consisting of rubber-modified vinyl (co)polymers in granulate form and rubber-free vinyl (co)polymers, D) from 0.002 to 0.200 part by weight, based on the sum of components A+B+C+D+E, of at least one Brönsted acid, E) from 0.1 to 40.0 parts by weight, based on the sum of components A+B+C+D+E, of one or more additives, with the exception of the Brönsted acid according to component D, the process comprising:
