Abstract
PURPOSE: To eliminate the deposition of copper and polymer discoloration and lowering of viscosity in the polymerization and fiber making process, by adding a solution, obtained from the reaction of copper with a specific mixed solvent, to the polymerization system.
CONSTITUTION: (A) Copper metal or a cuprous halide is reacted with (B) a mixture of (a) aqueous ammonia in a molar amount of 1W2 times that of (A) and (b) a hydrohalogenic acid in a molar amount of 1W20 times that of A. 10W10,000ppm, preferably 30W500ppm of the solution thus obtained is added to the polymerization system. Cuprous iodide is preferably used as (A); hydriodic acid, as (B).
