Polyamide based thermoplastic molding materials containing an impact modifier and a copper compound useful for production of fibers, films (claimed), for synthetic plastic hollow bodies, especially siphons and Venturi tubes

摘要

A novel thermoplastic molding composition contains: (A) polyamides; (B) smoothed fiber type filler; (C) straight chain carboxylic acid salt of chain length (including the terminal carboxyl carbon atom) at least 20, preferably at least 24 carbon atoms; (D) alkali metal halide, a copper(I) compound; and optionally (E) a colorant soluble in polyamide; (F) an impact modifier; and/or (G) further additives. A novel thermoplastic molding composition contains (wt.%): (A) polyamides (1-99.889); (B) smoothed fiber type filler (0.1-50); (C) straight chain carboxylic acid salt of chain length (including the terminal carboxyl carbon atom) at least 20, preferably at least 24 C atoms (0.01-0); (D) alkali metal halide, copper(I) compound (0.00-7); optionally (E) a colorant soluble in polyamide (0-3); (F) an impact modifier (0-35); and/or (G) further additives (0-30). Independent claims are included for: (1) a synthetic plastic shaped body or single-piece synthetic plastic hollow body containing thermoplastic shaped bodies; and (2) synthetic plastic building parts, especially multi-piece synthetic plastic hollow bodies, including at least two synthetic plastic shaped bodies joined by ultrasonic, laser, hot element, or vibration welding, containing thermoplastic molded bodies.
