Abstract
The invention relates to a nanocomposite which comprises a polyamide component (A) and a nanoparticulate component (B), wherein nanoparticulate component (B): a) is based on at least one oxide or mixed oxide/ oxide hydrate of one or more metals or half metals M, b) has a mean particle diameter of up to 10 nm, and c) is obtainable in a process comprising sol-gel synthesis that is carried out in the presence of an acid. The invention also relates to methods of making polyamide nanocomposites and to the use of nanoparticulate components to increase the flow of polyamide containing melts. The invention furthermore relates to molded parts made of the nanocomposite and to the use of a nanocomposite to produce thin-walled molded parts.
