Abstract: The present invention relates to compositions comprising (i) at least one molding compound comprising the components A and B as component (I), where A) means a graft copolymer as component A, and B) means a thermoplastic copolymer as component B; and (ii) at least one cyclohexane polycarbolic acid derivate of the formula (I); as component (II) where R
1 stands for C
1 -C
10 -alkyl or C
3 -C
8 -cycloalkyl, m stands for 0, 1, 2, or 3, n stands for 2, 3, or 4, and R stands for hydrogen or C
1 -C
30 -alkyl; or the group -(COOR)
n forms an anhydride of the formula (II), wherein, according to the invention, the component (I) comprises 11 to 19.9% by weight of component A and 80.1 to 89% by weight of component B, wherein each % by weight is based on the sum of components A and B and together adds up to 100% by weight. The invention further relates to a method for producing the composition according to the invention, to the use of the composition according to the invention for producing molded parts, films, foams or fibers, and to molded parts, films, foams or fibers comprising the composition according to the invention.
