Tube, and polyamide resin composition |
| abstract |
Provided is a tube comprising a layer containing: 60-80 mass% of a semi-aromatic polyamide; and 15-40 mass% of an elastomer modified with an unsaturated compound having at least one selected from among a carboxyl group and an acid anhydride group, wherein the layer has a phase-separated structure including a phase (A) containing the semi-aromatic polyamide and a phase (B) containing the elastomer, the phase (A) being a continuous phase, and the phase (B) being a dispersion phase dispersed in the phase (A), and in a cross-sectional image of the layer as observed by an electron microscope, the average number of the phase (B) having a major axis diameter of at least 2 μm and existing per 100 square μm, is at most 1/100 μm2. Also provided is a polyamide resin composition obtained by melt-kneading a semi-aromatic polyamide and an elastomer modified with an unsaturated compound having at least one selected from among a carboxyl group and an acid anhydride group, wherein the total concentration of the carboxyl group and the acid anhydride group in 1 g of the elastomer is 85-250 μeq/g. |
