Abstract: Foam particles that have a bulk density below 300 kg/m3 and are based on polyamides, including 85% to 100% by weight of at least one copolyamide obtainable by polymerizing the following components:



(A) 15% to 84% by weight of at least one lactam,
(B) 16% to 85% by weight of a monomer mixture (M) including the following components:

(B1) at least one C32-C40 dimer acid and
(B2) at least one C4-C12 diamine,
wherein the monomer mixture (M) includes in the range from 45 to 55 mol % of component (B1) and in the range from 45 to 55 mol % of component (B2), based on the total molar amount of the monomer mixture (M), and the sum total of the components of (A) and (B) is 100% by weight, and processes for production thereof.
