    Abstract: A thermoplastic molding composition comprising a specified mixture containing (a) a methyl methacrylate (co)polymer, (b) a vinyl aromatic-vinyl cyanide copolymer, (c) a graft copolymer and optionally (d) conventional additives is such that (1) the copolymeric core used for graft copolymer (c) has a monomodal particle size distribution and an average particle size (D 50) as measured by a described method of 300-400 nm; and (2) the difference of the refractive index of the total composition used to produce (c) and that of the (a)/(b) matrix is 0.003-0.008 as measured by a specified method. A thermoplastic molding composition comprising a specified mixture containing (c) a graft copolymer is such that (1) the copolymeric core used for graft copolymer (c) has a monomodal particle size distribution and an average particle size (D 50) as measured by a described method of 300-400 nm; and (2) the difference of the refractive index of the total composition used to produce (c) and that of the matrix based on the other polymers is 0.003-0.008 as measured by a specified method. The specified mixture comprises by weight (A) a methyl methacrylate polymer (30-69%) obtained by polymerization of (i) methyl methacrylate (90-100%) and (ii) a 1-8C alkyl acrylate (0-10%); (B) a copolymer (30-69%) obtained by copolymerization of (iii) a vinyl aromatic monomer (75-88%) and (iv) a vinyl cyanide (12-25%); (C) a graft copolymer (1-40%) comprising a core polymer (60-90%) obtained from (v) a 1,3-diene (65-89.9%), (vi) a vinyl aromatic monomer (10-34.9%) and (vii) an agglomeration polymer together with a first shell (5-20%) obtained by polymerization of (viii) a vinyl aromatic monomer (30-39%), (ix) a 1-8C alkyl methacrylate (61-70%) and (x) a crosslinking monomer (0-3%) and a second shell (5-20%) obtained by polymerization of (xi) a 1-8C alkyl methacrylate (70-98%) and (xii) a 1-8C alkyl acrylate (2-30%), the weight ratio first : second shell being 2 : 1-1 : 2; and optionally (D) conventional additives (up to 20%). An independent claim is also included for production of the mixtures by melt mixing of the components.
