Synthesis of Ultrahigh Molecular Weight Nylon 4 with Onium Salt and Crown Ether-Containing Catalysts

  • R. Bacskai
Part of the Polymer Science and Technology book series (POLS)


The discovery of Ney, Nummy, and Barnes,1 that 2-pyrrolidone can be polymerized to nylon 4 by basic catalysts, stimulated much subsequent work on the preparation, physico-chemical characterization, and utilization of the polymer. The great interest in this polymer is due to the fact that nylon 4 textile fibers combine the good strength properties of nylon 6 or 66 with the hydrophilicity of cotton.2
