Abstract
The present invention relates to impact-modified polyester/polycarbonate compositions containing: A) 41 to 80 parts by weight, in each case relative to the sum of the parts by weight of components A+B+C+D, of aromatic polycarbonate, B) 5 to 40 parts by weight, in each case relative to the sum of the parts by weight of components A+B+C+D, of polyester with a content of isophthalic acid building blocks, C) 1 to 15 parts by weight, in each case relative to the sum of the parts by weight of components A+B+C+D, of rubber-modified graft polymer, D) 0 to 25 parts by weight, in each case relative to the sum of the parts by weight of components A+B+C+D, of a flame retardant, E) 0 to 20 parts by weight, in each case relative to the sum of the parts by weight of components A+B+C+D=100, of vinyl (co)polymer, F) 0 to 50 parts by weight, in each case relative to the sum of the parts by weight of components A+B+C+D=100, of additives, wherein all the stated parts by weights in the present application are normalized such that the sum of the parts by weight of components A+B+C+D in the composition amounts to 100, which exhibit improved elongation at break in conjunction with excellent multiaxial toughness and low molding shrinkage. Provided that these compositions have been rendered flame-retardant, they exhibit flame retardant properties which are equal to or better than known compositions.
