Estimating the term…
An object is to solve the problem that no reports have yet been made on a pure polyether nitrile that exhibits a semi-crystallization time of less than 120 seconds, which is considered to be a practical molding cycle, and provide a polyether nitrile from which a molded article can be produced with improved efficiency. As a solution, a polyether nitrile having a semi-crystallization time of 100 seconds or less at 275° C., the semi-crystallization time being determined by power-compensated differential scanning calorimetry when the polyether nitrile is cooled from a molten state at 370° C. to 275° C. at a cooling rate of 500° C. per minute, is provided.
A polyether nitrile having a semi-crystallization time of 100 seconds or less at 275° C., the semi-crystallization time being determined by power-compensated differential scanning calorimetry when the polyether nitrile is cooled from a molten state at 370° C. to 275° C. at a cooling rate of 500° C. per minute.
A method for producing a polyether nitrile resin composition, comprising mixing two or more raw-material polyether nitriles having different weight-average molecular weights with at least one selected from the group consisting of (A) to (C):
