Abstract: The present disclosure relates to processes for producing high molecular weight polyamides from caprolactam. In particular, the present disclosure relates to processes for adding water during Solid State Polymerization (SSP) to remove residual caprolactam to form high molecular weight polyamides, e.g., Nylon 6 and Nylon 6,6 copolymers, having low residual caprolactam monomer content. The water addition step controls the SSP process for a specific time to produce polyamides with a desired molecular weight and low residual caprolactam monomer content.
