研究了五种新型活性三嗪类偶氮染料及其中间体的合成。这些染料中的三种含有四甲基哌啶（TMP）片段，其中四种在其分子中含有可聚合基团。研究了两种不同的合成反应方案，确定了最佳的合成方案，并采用薄层色谱法对合成过程进行了定量监测。对棉织物进行染色，并测定其颜色特性。用丙烯酰胺（ACA）和丙烯腈（AN）共聚得到染料，并得到对溶剂萃取稳定的浓橙子共聚物。研究了染料在溶液中和棉织物上的光稳定性，发现其中两种含TMP片段的染料具有良好的光稳定性，可推荐使用。
The synthesis of five new reactive triazine azodyes and their intermediates was investigated. Three of these dyes contained a tetramethylpiperidine (TMP) fragment and four of them contained a polymerizable group in their molecule. Two different reaction schemes for synthesis were studied and the most suitable one was found. The quantitative thin-layer chromatography (Tlc) to monitor the synthesis was applied. Cotton fabrics were dyed and their color characteristics were measured. The dyes copolymerized with acrylamide (ACA) and acrylonitrile (AN) and the copolymers with an intense orange color that is stable to solvent extraction were obtained. The photostability of the dyes in solution and on cotton fabrics was studied and it was found that two of the dyes, containing a TMP fragment, had good photostability and can be recommended.
