  • Continuous low moisture catalytic method for polymerization of caprolactam
    Patent number: 4471081
    Abstract: This invention is an improvement to the continuous method to polymerize caprolactam at temperatures over 220.degree. but below 280.degree. C. in the presence of free water, a catalyst capable of generating phosphoric acid at the reaction conditions, in the hydrolyzer to form a prepolymer, with subsequent stripping of water and other low boiling compounds, and with completion of polymerization in a final finisher under a vacuum. The improvement comprises limiting the amount of free water fed to the polymerization process to less than about 1.5 percent but above 0.
