PROMOTION OF .epsilon.-CAPROLACTAM BLOCK COPOLYMERIZATION ABSTRACT A process for polymerizing .epsilon.-caprolactam to form a nylon-6 block copolymer in which a reactant stream containing .epsilon.-caprolactam, and a lactam poly- merization initiator is brought into polymerizing admixture with a reactant stream containing .epsilon.-capro- lactam and a lactam magnesium halide, wherein suffi- cient 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. The lactam polymerization initiator is a telechelic oligomer or polymer containing a backbone which provides elastomeric segments in the nylon-6 block copolymer, and attached to the backbone are activated initiator groups which initiate the polymerization of .epsilon.-caprolactam in the presence of the lactam magnesium halide.
