Nylon-6 fibers were phosphorylated with diisopropyl phosphorochloridate (DIPC), and the reaction was confirmed by ir spectra. The phosphorus content and percentage of carbon residue were determined. The effect of the reaction temperature, the molar ratio of reactants, and the time of reaction were studied. It was found that the increase in reaction temperature from 30 to 80°C results in a slight increase in phosphorus content, while a relatively considerable increase in phosphorus content was observed when the temperature increased to 110°C. It was also observed that the carbon residue is directly proportional to the increase in phosphorus content. It was found that the best results were obtained with the ratio DIPC:base mole of nylon of 2:1, a temperature of 110°C, and a time of 2 h.
