用聚丙烯酰胺Hofmann降解制得的聚乙烯胺与2，4-二硝基氯苯反应，合成了一种新型黄色交联聚乙烯胺染料。以1，3，5-三氯均三嗪和2-（对氨基苯磺酰基）乙基硫酸钠为原料合成交联剂，将其交联并染色到棉和丝绸上。研究了聚乙烯胺黄色染料的交联/染色条件，如pH值、固化温度和交联剂浓度。该交联剂对棉和丝绸的固色率均大于99%。通过比较未染色纤维、染色纤维和交联纤维的红外光谱，以及通过用DMF/水（1：1）萃取交联和染色的样品没有染料从样品上剥离的事实，间接证明了交联共价染料-纤维键。© 2006 Wiley Periodicals，Inc.应用聚合物科学杂志102：1568-1573，2006
A new, yellow crosslinking polyvinylamine dye was synthesized by the reaction of 2,4-dinitrochlorobenzene with polyvinylamine prepared from Hofmann degradation of polyacrylamide. It was crosslinked and dyed to cotton and silk by a crosslinker synthesized from 1,3,5-trichloro-s-triazine and sodium 2-(p-aminophenylsulfonyl)ethyl sulfate. The crosslinking/dyeing conditions of the yellow polyvinylamine dye, such as pH, cure temperature, and concentration of the crosslinker were investigated. The fixations of the polymeric dye by the crosslinker on cotton and silk were greater than 99%. The crosslinking covalent dye–fiber bond was proved indirectly by the comparison of IR spectra of the undyed fiber, the dyed fiber, and the crosslinked one, and also by the fact that no dye was stripped off from the crosslinked and dyed sample by extraction with DMF/water (1 : 1). © 2006 Wiley Periodicals, Inc.
