Abstract: Disclosed are retrofit processes for retrofitting a polymer production apparatus to produce a plurality of polymer products. The retrofit process may comprise modifying an existing primary manifold to include a retrofit manifold and at least one additive injection apparatus. The retrofit process may also comprise modifying an existing secondary manifold to include an additive injection line and a polymer solidifier in contact with the secondary manifold. The retrofitted polymer production apparatus produces varied finished polymer products from one continuous polymerization reactor.

Abstract: Process for incorporating additives into a polymer utilizing a polymerization reactor in fluid communication with a primary manifold carrying the liquid polymer. The primary manifold is in fluid communication with at least one secondary manifold comprising an additive injection line. The process produces varied finished polymer products from one continuous polymerization reactor.

Abstract: Described herein are methods of preparing high molecular weight polyamides which reduce or eliminate the production of unwanted gels during the production process. These methods reduce the formation of undesired polyamide gel by polishing the internal surfaces of the production equipment, thereby providing surfaces with smaller surface roughness values.
