Abstract: The disclosure relates to apparatuses and methods for production of polyamide polymers utilizing additive injectors. In one embodiment, an apparatus for batch production of a polyamide polymer is provided. The apparatus can include a salt strike vessel configured to produce a polyamide salt composition and an evaporator configured to reduce water content of the polyamide salt composition to produce a polymerizable polyamide composition. The apparatus can further include a first autoclave operably connected to the evaporator such that a first portion of the polymerizable polyamide composition is deliverable from the evaporator to the first autoclave, and a second autoclave operably connected to the evaporator such that a second portion of the polymerizable polyamide composition is deliverable from the evaporator to the second autoclave. The first additive injector can be associated with the first autoclave and can be configured to inject additives into the first autoclave.
