ABSTRACT:
A process for polymerizing .epsilon.-caprolactam to form a nylon-6 polymer in which a reactant stream containing .epsilon.-caprolactam and a lactam polymerization initiator is brought into polymerizing admixture with a reactant stream containing .epsilon.-caprolactam and a lactam magnesium halide, wherein sufficient 2-oxo-1-pyrrolidinyl compound is added to the admixture either as 2-pyrrolidinone, 2-oxo-pyrrolidinyl magnesium halide or 2-oxo-1-pyrrolidinyl capped initiator compound to enhance the rate of polymerization of the .epsilon.-caprolactam.
