Assignee: BASF SE
Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C | IPC C

Claim 0:
1. 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) comprising components
B1′) at least one C32-C40-dimer acid and
B2′) at least one C4-C12-diamine,, wherein 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 comprising using the copolyamides c) to increase an impact strength and/or breaking elongation of molded articles made of thermoplastic molding materials comprising thermoplastic polyamides, which are different from copolyamides c),, wherein the thermoplastic molding materials comprise
a) 44.0 to 98.8% by weight of at least one thermoplastic polyamide which is different from copolyamide c) as component A),
b) 1.0 to 50.0% by weight of at least one elastomer as component B), selected from the group consisting of
b1) copolymers of ethylene with at least one comonomer selected from the group consisting of
C3-12-olefins, C1-12-alkyl (meth)acrylates, (meth)acrylic acid and maleic anhydride as component B1), and
b2) polyethylene or polypropylene as component B2), grafted with maleic anhydride,

wherein component B1) is optionally additionally grafted with maleic anhydride,
c) 0.2% to 10% by weight of at least one copolyamide c) as component C),
d) 0% to 60% by weight of glass fibers as component D), and
e) 0% to 30% by weight of further additives and processing aids as component, wherein the weight percentages for the components A) to E) sum to 100% by weight.
