| titleOfInvention | Polyamide resin, composition containing said polyamide resin, and molded body containing said polyamide resin and composition |
| abstract | Provided is a polyamide resin excelling in moldability, and also excelling in mechanical properties (tensile elastic modulus and tensile elongation, specifically, tensile fracture point elongation) when formed into a molded body. The polyamide resin has a concentration of terminal carboxyl groups of 100 μeq/g or greater, and a [ηrel/ηrc] of greater than 0.91 and less than 1.13. ηrel: The relative viscosity measured in accordance with the JIS K 6920 standard (in 96% sulfuric acid, polymer concentration of 10 mg/ml, 25℃). ηrc: The relative viscosity calculated by an approximation equation (1) from the number average molecular weight Mn or less. Equation (1): ηrc = K × Mnα (In the equation: K and α are constants determined by measuring the number average molecular weight Mn and relative viscosity ηrel of at least any three polyamide resins of the same type as the aforementioned polyamide resin, and fitting the measured values into equation (1) as Mn and ηrc, respectively; and Mn is the number average molecular weight of the polyamide resin and is calculated from the terminal carboxyl group concentration (μeq/g) and a terminal amino group concentration (μeq/g).) |
