Abstract:
The present disclosure relates to a preparation of polymer with improved color and properties. More particularly, the disclosure relates to the preparation of polyamide by introducing a polyetheramine additive during the polymer extrusion step. The extruded polymer is superior in appearance and spinnable in subsequent processing into yarn.
