<p>A transparent polyamide molding compound comprises polyamide molding compound containing copolyamide (A1) constructed from bis-(4-amino-3-methyl-cyclohexyl)methane (MACM), isophthalic acid (IPS) and laurinlactam (LC 12); a transparent polyamide (A2); an aliphatic polyamide based on monomers (A3) selected from diamines, dicarboxylic acids, lactams and amino carboxylic acids; at least one lubricant (B1) selected from salts of stearic acid, isotridecylstearate and/or salts of montanic acids; and further additives (C1). A transparent polyamide molding compound containing at least one copolyamide and one lubricant comprises, the polyamide molding compound containing (part by weight): a copolyamide (A1) (50-99.99), constructed from (a) bis-(4-amino-3-methyl-cyclohexyl)methane (MACM) (15-45) mol.%, which can be replaced by bis-(4-amino-cyclohexyl)methane (PACM) and/or hexamethylenediamine (HMDA) (up to 50) mol.%, (b) isophthalic acid (IPS) (15-45) mol.%, which can be replaced by terephthalic acid (TPS) and/or aliphatic dicarboxylic acids (up to 50) mol.%, and (c) laurinlactam (LC 12) (10-70) mol.%; a transparent polyamide (A2) (0-49.99) based on MACM and/or PACM and dicarboxylic acids with at least 9C-atoms; an aliphatic polyamide based on monomers (A3) (0-29.99) selected from diamines with at least 8C-atoms, dicarboxylic acids with at least 10-C atoms, lactams with at least 10 C-atoms and amino carboxylic acids with at least 10C-atoms, the sum of (A2) and (A3) is at most (49.99); and at least one lubricant (B1) (0.01-5) selected from salts of stearic acid, isotridecylstearate and/or salts of montanic acids; and further additives (C1) (0-3), with the proviso that the sum of (A1), (A2), (A3) and (B1) produces 100 parts by weight. An independent claim is included for molded article produced from a transparent polyamide molding compound.</p> |
