Abstract: Disclosed are nylon salt solution preparation processes including a trim diamine feed. The trim diamine is added to a recirculation loop in a continuous stirred tank reactor, where it is blended with the nylon salt solution via a pump. The nylon salt solution is prepared by feeding a dicarboxylic acid monomer and a diamine monomer to a single continuous stirred tank reactor. The dicarboxylic acid is metered, based on weight, from a loss-in-weight feeder to the reactor. The nylon salt solution is formed continuously and has low variability from a target pH and/or a target salt solution concentration. The nylon salt solution is transferred directly to a storage tank, without further monomer addition, pH adjustment, or salt solution adjustment after exiting the continuous stirred tank reactor.

Abstract: The present disclosure provides methods and apparatuses providing uniform polyamide pellets. In one example, a method can include maintaining a vacuum during a pre-casting polymerization cycle of the cyclic process such that the pre-casting polymerization cycle produces a reactive polyamide polymer with decreased pre-casting polymerization cycle time, extruding the reactive polyamide polymer during a casting cycle by adjusting process parameters including vessel pressure and extrusion valve opening to generate a throughput of extruded polymer, and cutting the extruded polymer at a cutting speed substantially proportional to the throughput to provide polyamide pellets.
