A) from 2 to 99.8% by weight of at least one polyester, B) from 0 to 49.9% by weight of a rubber-free copolymer different from C) and/or G) made of
b1) from 60 to 95% by weight of styrene or of substituted styrenes of the general formula Ia or a mixture of these in which R is an alkyl radical having from 1 to 8 carbon atoms or a hydrogen atom, and R1 is an alkyl radical having from 1 to 8 carbon atoms, and n has the value 1, 2, or 3, andb2) from 5 to 40% by weight of at least one unsaturated nitrile, C) from 1 to 49.9% by weight of one or more impact-modified graft rubbers having no olefinic double bond in the rubber phase, wherein said one or more graft rubbers have a swelling index from 6 to 60 (in toluene), and wherein component C) is a graft polymer composed of
C1) from 40 to 80% by weight of a graft base made of an elastomeric polymer based on alkyl acrylates having 1 to 8 carbon atoms in the alkyl radical and with glass transition temperature below 10° C.,C2) from 20 to 60% by weight of a graft made of
C21) from 60 to 85% by weight of styrene or of substituted styrenes of the general formula Ia or a mixture of these,C22) from 15 to 35% by weight of at least one unsaturated nitrile, D) from 0.1 to 1% by weight of a compound of the formula (I) E) from 0.1 to 1% by weight of a mixture of compounds of the formula (II) F) from 0 to 1% by weight of a mixture of compounds of the formula (III) or from 0 to 1% by weight of a mixture of compounds of the formula (IV) or from 0 to 1% by weight of a mixture of compounds of the formula (V): or from 0 to 1% by weight of a mixture of compounds of the formula (VI) or a mixture of these, G) from 0 to 30% by weight of a copolymer made of
g1) from 49.5 to 99.5% by weight of structural units deriving from one or more vinylaromatic monomers,g2) from 0 to 50% by weight of structural units deriving from one or more vinyl cyanides,g3) from 0.5 to 40% by weight of structural units deriving from one or more dicarboxylic anhydrides, andg4) from 0 to 25% by weight of structural units deriving from other copolymerizable monomers,where each of the % by weight values for component G) is based on the total weight of the structural units deriving from components g1, g2, g3, and g4, and the total of these values is 100% by weight, and H) from 0 to 60% by weight of other additives, wherein the total of the percentages by weight of A) to H) do not exceed 100% by weight. |
