Process and formulation for producing a polyamide having low caprolactam concentration and specific relative viscosity

A base polyamide composition comprising a nylon mixture having caprolactam units from 1 wppb to 50 wppm catalyst composition; and greater than 0.75 wt% residual caprolactam, wherein the base polyamide composition has a delta end group level ranging from 30 [mu]eq/gram to 90 [mu]eq/gram.
