Abstract: A method for producing a polyamide resin characterized by comprising thermally polycondension of tetramethylene diamine and either an aliphatic dicarboxylic acid having 7 or more carbon atoms or a salt thereof, and then being melt-polymerized at a temperature equal to or higher than the melting point thereof until the relative viscosity of a 0.01 g/ml solution thereof in 98% sulfuric acid solution with a 0.01 g/ml content at 25 °C becomes 2.2-5.0.

Abstract: A polyamide resin composition which is obtained by melt-kneading (A) a polyamide resin, (B) a phyllosilicate, and (C) either an olefin compound having a carboxylic acid anhydride group in the molecule or a polymer of the olefin compound, wherein the phyllosilicate (B) is one in which exchangeable metal ions present between layers thereof have undergone ion exchange with an organic onium salt and which has reactive functional groups bonded thereto. The composition combines high rigidity with stretchability even when it has a low ash content. It may optionally contain an inorganic filler other than the phyllosilicate, an impact modifier, and a flame retardant. In this case also, the composition retains rigidity and stretchability.
