本文用 GPC方法测定了聚 N-乙烯咔唑中残留单体含量,测定精确度约为±2％,聚合物中单体的最小检知量为0.03％。并且讨论了凝胶的孔径、溶剂纯度及不同检测器对结果的影响。 In this paper, the content of residual monomers in poly (N-vinylcarbazole) was determined by GPC method. The determination accuracy was about ± 2%. The minimum detectable amount of monomer in the polymer was 0.03%. The pore size, solvent purity and the effect of different detectors on the results were also discussed.
