Abstract: Described herein is a method of using copolyamides c) produced by polymerization of components



A′) 15% to 84% by weight of at least one lactam, and
B′) 16% to 85% by weight of a monomer mixture (M) including components
B1′) at least one C32-C40-dimer acid and
B2′) at least one C4-C12-diamine,
where the percentages by weight of the components A′) and B′) are in each case based on the sum of the percentages by weight of the components A′) and B′),
the method including using the copolyamides c) to increase an impact strength and/or breaking elongation of molded articles made of molding materials including thermoplastic polyamides, which are different from copolyamides c).
