  • POLYAMIDE NANOCOMPOSITES WITH HYPER-BRANCHED POLYETHERAMINES
    Publication number: 20110021686
    Abstract: The invention relates to thermoplastic molding compositions comprising the following components: A) at least one thermoplastic polyamide, B) at least one hyperbranched polyetheramine, C) at least one amorphous oxide and/or oxide hydrate of at least one metal or semimetal with a number-average diameter of the primary particles of from 0.5 to 20 nm. The invention further relates to the use of the components B) and C) mentioned, for improving the flowability and/or thermal stability of polyamides, to the use of the molding compositions for the production of fibers, of foils, and of moldings of any type, and also to the resultant fibers, foils, and moldings.
