Abstract:
1. A polyamide molding material for the production of transparent or colorable moldings with high flexibility, high notched impact strength (Charpy), low water absorption and excellent chemical resistance, comprising: 40 to 100% by weight of at least one partly crystalline, transparent copolyamide (A) with a glass transition temperature (T the copolyamide (A) consisting of: one of the diamines is a linear aliphatic diamine selected from the group consisting of: 1,10-decanediamine, 1,11-undecanediamine, and 1,12-dodecanediamine, and one of the diamines is a cycloaliphatic diamine, selected from the group consisting of: bis(4-amino-3-methylcyclohexyl)methane (MACM), 2,2-bis(4-amino-3-methylcyclohexyl) propane, bis(4-amino-3-ethylcyclohexyl)methane (EACM), bis(4-amino-3,5-dimethylcyclohexyl)methane (TMACM), isophoronediamine (5-amino-1,3,3-trimethylcyclohexanemethanamine, 1,3-diaminocyclohexane, 1,3-diaminomethylocyclohexane, 2,5- or 2,6-bis-(aminomethyl) norbornane (DN), and 2,t- or 2,6-diaminonorbornane, where the concentration of the cylcoaliphatic diamine is 10 to 40 mol % and the concentration of the linear aliphatic diamine is at least 60 mol %, based in each case on the total diamine content and 0 to 60% by weight of at least one further polymer (B) selected from the group consisting of: amorphous homopolyamides, amorphous copolyamides, partly crystalline homopolyamides, partly crystalline copolyamides, polyether ester amides, polyether amides, and polyester amides; and 0 to 10% by weight of customary additives (C) selected from the group consisting of: UV stabilizers, free-radical scavengers, lubricants, mold release aids, plasticizers, optical brighteners, dyes, color pigments, flame retardants, heat stabilizers, processing aids, additives that influence optical properties, impact modifiers, fillers and mixtures thereof, where the sum of components (A), (B) and (C) adds up to 100% by weight.
