| Abstract: | A high\|performance liquid chromatographic method (HPLC) was adopted to determine ε\|caprolactam and its cyclic oligomers in nylon 6 chip. The chromatographic conditions were optimized by selecting a methanol\|water mixture as mobile phase and gradient elution seperating cyclic oligomers so that the peaks were seperated well. The shortening of analytical time to 15 min was advantageous to the determination of high oligomers. The effects of polymerization time and initial water content on cyclic oligomers were also discussed. |
