Title:
POLYETHER NITRILE WITH IMPROVED CRYSTALLIZATION SPEED, METHOD FOR PRODUCING SAME, POLYETHER NITRILE RESIN COMPOSITION, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2024/053304
Kind Code:
A1
Abstract:
The fact that pure polyether nitrile exhibiting a half-crystallization time of less than 120 seconds (i.e., the time considered to be a practical molding cycle) has not previously been reported represents a problem. The present invention attempts to solve this problem and addresses the problem of providing a polyether nitrile that makes it possible to improve the productivity of a molded product. As a solution, the present invention provides polyether nitrile having a half-crystallization time of 100 seconds or less at 275ºC as measured by input compensation-type differential scanning calorimetry when the temperature is lowered from a molten state at 370ºC to 275ºC at a cooling rate of 500ºC per minute.
