<p>The present invention relates to thermoplastic molding compounds containing a mixture of the following: A) at least one methyl methacrylate polymer; B) at least one copolymer, obtainable by the polymerization of a mixture consisting of (B1) at least one vinyl aromatic monomer and (B2) at least one vinyl cyanide as monomers; C) at least one graft copolymer, obtainable from a core and a first graft shell and a second graft shell; D) at least one poly(butyl acrylate) with a molecular weight of 1700 to 4000 g/mol (determined as the MW by gel permeation chromatography); and E) optionally, conventional additives as component (E); a method for the production of these thermoplastic molding compounds, the use of these thermoplastic molding compounds for the production of molded objects, and the use of styrene-methyl methacrylate copolymers with a molecular weight of 1700 to 4000 g/mol (determined as the MW by gel permeation chromatography) for improving the flowability and reducing the dependence of the impact strength and the haze value of thermoplastic molding compounds on injection conditions.</p> |
