description A thermoplastic molding composition is disclosed containing polycarbonate resin and a copolymer of methyl methacrylate conforming structurally to Formula (I) wherein x and y are integers calculated to result in a content of PMMA in the copolymer in the range of 80 to 90 mole %, and where R1 denotes -CH3, R2 denotes -C6H5 and R3 is a C1-C2-alkyl group. The composition is characterized in its transparence. L'invention porte sur un produit de moulage thermoplastique contenant une résine de polycarbonate et un copolymère de méthylméthacrylate conforme du point de vue de la structure à (I) dans laquelle: x et y sont des entiers calculés pour obtenir dans le polymère une teneur en PMMA de 80 à 90 mole %, R1 est -CH3, R2 est -C6H5 et R3 est un groupe C1-C2-alkyle. Cette composition se caractérise par sa transparence.
