Abstract: The disclosure relates to an improved method of producing MPMD based amorphous, semi-aromatic polyamides in order to improve their mechanical properties. It also relates to improved formulations of these polyamides which have further improved mechanical properties by the incorporation of greater amounts of isophthalic acid.

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.
