Abstract:
1. A molding composition for production of moldings with reduced surface gloss, which has a) from 50 to 99.8% by weight of a matrix (A) comprising one or more semicrystalline engineering thermoplastics selected from the group consisting of polyacetals, polyesters, polyamides and polyaryl sulfides, b) from 0.1 to 30% by weight of one or more particulate polymers (B) with a median size d c) from 0.1 to 30% by weight of one or more non-crosslinked thermoplastic polymers (C) which themselves reduce the gloss of the matrix (A) by at least 5%, and d) from 0 to 20% by weight of one or more inorganic or salt-like compounds (D) with a median size d wherein a molding produced from the molding composition comprises total formaldehyde and carbon emission values of less than 150 ppm and a moduli of elasticity greater than 2000 MPa, and wherein the mattness value of a comparison molding produced without components B, C, and D is at least 60% lower than a molding produced from the molding composition.
