Zusammenfassung:Molding composition for producing high gloss, rigid polyamide shaped articles comprises 100 parts polyamide (PA) mixture (A); 40-235 parts reinforcing filler (B) and usual PA formulation additives (C). Molding composition for producing high gloss, rigid polyamide shaped articles comprises 100 parts polyamide (PA) mixture (A); 40-235 parts reinforcing filler (B) and usual PA formulation additives (C). (A) contains, by weight: (I) 0.5-95% semicrystalline linear PA; (II) 5-99% branched graft PA; (III) 0.5-40% amorphous PA; and (IV) 0-2% carbon black. (i) has a styrene-maleimide basic structure of formula (1) and/or (ii) is produced by hydrolytic polymerization of amino acids and/or lactams as basic components, with addition, to the melt of these components, of the following branching components (i) 5-150 mumole/g polymer of at least one trifunctional monomer, derived from an amine or carboxylic acid monomer, and (ii) 2-100 mumole/g polymer of an at least bifunctional monomer, i.e. a carboxylic acid when (i) is derived from an amine or an amine when (i) is derived from a carboxylic acid. m = 1-5; n = 3-15, such that molecular weight of the basic structure is 600-9000; X indicates the position of the grafted polyamino acid sidechain . An Independent claim is also included for shaped articles prepared from the new composition.
