Abstract:
1. A polymer composition, which comprises a polymer component comprising at least one at least semicrystalline polymer having no ionic groups, and 0.1 to 30% by weight of at least one ionic liquid, as plasticizer, wherein the semicrystalline polymer is a thermoplastically processable polymer selected from the group consisting of (co)polyamides, (co)polyesters, polyurethanes, polyphenylene ethers, polyolefins, (co)polyetheramides, polyaramides, polyether(ether)ketones, and polyetheresteramides, and the ionic liquid is a salt having a cation of the following structures: where R1, R2, R3, R4, R5, and R6 are identical or different, and are hydrogen, a linear or branched aliphatic hydrocarbon radical having from 1 to 20 carbon atoms, a cycloaliphatic hydrocarbon radical having from 5 to 30 carbon atoms, an aromatic hydrocarbon radical having from 6 to 30 carbon atoms, an alkylaryl radical having from 7 to 40 carbon atoms, a linear or branched aliphatic hydrocarbon radical having from 2 to 20 carbon atoms and having interruption by one or more heteroatoms (oxygen, NH, NCH
