    Abstract: Provided is a polyamide resin composition comprising a melt blend of (A) a polyamide resin, (B) a phyllosilicate, and (C) an olefin compound having a carboxylic acid anhydride group in the molecule or a polymer of the olefin compound, in which the phyllosilicate (B) has a reactive functional group bonded thereto and is such that the exchangeable metal ions existing in the interlayers are ion-exchanged with organic onium ions. The composition has a reduced inorganic ash content and has both high stiffness and high ductility. Optionally, the composition contains an inorganic filler apart from the phyllosilicate, an impact modifier, and a flame retardant, still having high stiffness and high ductility.

    Abstract: A polyamide resin obtained by heating and condensation-polymerizing ingredients mainly comprising pentamethylenediamine having a total content of 2,3,4,5-tetrahydropyridine and piperidine of 0.10 wt.% or lower and an aliphatic dicarboxylic acid having 7 or more carbon atoms, a 0.01 g/mL solution of the polyamide resin in 98% sulfuric acid having a relative viscosity at 25 °C of 1.8-4.5. The polyamide resin has excellent heat resistance, extremely low water absorption, and excellent melt residence stability and is hence suitable for use as long molded articles represented by automotive radiator tanks, etc.

    Abstract: The present invention addresses the problem of providing a high molecular weight, terminal modified polyamide resin having a low melt viscosity and excellent molding processability. The problem is solved by a terminal modified polyamide resin having a relative viscosity (·r), as measured at 25°C in a 98% sulfuric acid solution at a resin concentration of 0.01 g/ml, of 2.1 to 10, the resin comprising 0.05 to 4.5% by mass of a terminal structure represented by general formula (I): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-X-(R 1 -O) n -R 2 €ƒ€ƒ€ƒ€ƒ€ƒ(I) wherein n ranges from 2 to 100; R 1 represents a hydrocarbon group of 2 to 10 carbon atoms; R 2 represents a hydrocarbon group of 1 to 30 carbon atoms; -X- represents - NH- or -N(CH 3 )-; and n R 1 s in the general formula (I) may be the same or different.
