Abstract: PURPOSE:To obtain a part for an exhaust system for automobile having heat- resistance, rigidity, toughness and resistance to traffic antifreezing agent, by molding a mixture composed of a polyamide such as nylon 6, a higher polyamide such as nylon 11 and an inorganic reinforcing material. CONSTITUTION:The composition for the objective fan is produced by (1) mixing (A) 5-95wt.%, preferably 20-80wt.% of a polyamide containing capramide and/or hexamethylene adipamide as main constituent units (e.g. nylon 6 or nylon 66) and (B) 5-95wt.%, preferably 20-80wt.% of a polyamide (e.g. nylon 11) produced by the melt-polymerization of one or more compounds selected from 11-12C aliphatic amino acid, lactam and an equimolar salt of a 6-12C aliphatic diamine and a 6-12C aliphatic carboxylic acid (excluding hexamethylene diammonium adipate) and (2) compounding 100pts.wt. of the mixture produced by the above method with (C) 0-100pts.wt. of an inorganic filler (e.g. glass fiber).

Abstract: PURPOSE:To obtain a plastic automobile oil pan excellent in heat resistance, rigidity, toughness, resistance to road antifreezer, etc., by molding a mixture of at least two specified polyamides with an inorganic reinforcement. CONSTITUTION:5-95wt.% polyamide (e.g., nylon 6) consisting mainly of capramide and/or hexamethylene adipamide units is mixed with 95-5wt.% polyamide (e.g., nylon 12) obtained by melt-polymerizing at least one member selected from among a 1-12C aliphatic amino acid, a lactam and a equimolar salt of a 6-12C aliphatic diamine with a 6-12C aliphatic dicarboxylic acid (except hexamethylenediammonium adipate). 100pts.wt. this mixture is mixed with 0-100pts.wt. inorganic reinforcement (e.g., glass fiber), and the obtained mixture is molded into an automobile oil pan.
