Abstract
The present invention relates to novel molding compositions based on semicrystalline engineering thermoplastics which, in conventional processing techniques, give moldings with reduced surface gloss. A feature of the molding compositions is that they comprise, in a polymer matrix, if appropriate with the usual additives, polymer particles with a median size dof from 0.1 μm to 100 μm, and comprise at least one other incompatible or semicompatible polymer which has not been chemically crosslinked, and also, if appropriate, comprise salt-like additives. The invention further relates to moldings which are produced by means of conventional processing techniques, in particular via injection molding, from these matt-effect molding compositions.
