Impact resistance component and a polyoxamide resin excellent in impact resistance

摘要

(Ηr) is 2.1 or more relative viscosity number of carbon atoms of the diamine component consists of the diamine is 10 and 18, a solvent of 96% sulfuric acid, was measured at 25 ℃ concentration using a solution of 1.0g / dl polyoxamide resin excellent in impact resistance, which is characterized in that it is, and impact resistance component containing the resin. Sufficiently high molecular weight can be achieved relative to polyoxamide resin of conventional moldable temperature width estimated from the difference between the thermal decomposition temperature and melting point is wide, excellent melt-moldability, and further found in the aliphatic linear polyoxamide resin without impairing low water absorption that is, chemical resistance, hydrolysis resistance, high modulus, and high strength, as compared to aliphatic polyoxamide resin of conventional, impact resistance and polyoxamide resin excellent in impact resistance I provide the parts.
