Abstract
A thermoplastic molding composition having improved melt flow and chemical resistance is disclosed. The composition contains A) at least one member selected from the group consisting of aromatic polycarbonate and polyester carbonate, B) a graft polymer of at least one vinyl monomer on at least one rubber having a glass transition temperature of <10° C. as graft base and C) vinyl (co)polymer having weight-average molecular weight of 1500 to 5000 g/mol and glass transition temperature of >40° C. The composition may optionally further contain D) a phosphorus-based flame retardant and E) an anti-dripping agent.
