Synthesis and Characterization of Reactive Monomers Used as PDMDAAC Modification

摘要:

该文合成了3种具有反应性功能的单体，为获得新型的聚二甲基二烯丙基氯化铵（PDMDAAC）改性固色剂提供基础；以二烯丙基甲基胺、二烯丙基胺、三烯丙基胺及环氧氯丙烷为原料，分别合成了（3-氯-2-羟丙基）甲基二烯丙基氯化铵（CHMDAAC）、N,N-二烯丙基-3-羟基杂氮环丁烷氯化铵（DHAC）及（3-氯-2-羟丙基）三烯丙基氯化铵（CHTAAC）等反应性功能单体，对其结构进行了分析表征，并研究了其与基准单体二甲基二烯丙基氯化铵（DMDAAC）的共聚反应性。结果表明，所得单体具有预期结构，其收率为70%~95%，且与基准单体DMDAAC间可发生有效地共聚；可用于合成新的棉织物活性染料无醛固色剂用反应性PDMDAAC共聚改性聚合物。

Abstract:

In this article, three reactive functionated monomers were synthesized to put out a possibility to prepare the novel dye-fixatives of modified PDMDAAC. Those monomers such as 3-chloro-2-hydroxy-propylmethyldiallylammonium chloride (CHMDAAC), N, N-dially-3-hydroxy-azetidinium chloride (DHAC), and 3-chloro-2-hydroxypropyl triallylammonium chloride (CHTAAC) were synthesized by diallylmethylamine, diallylamine, triallylamine, and epichlorohydrin. In addition, the structures and ability of copolymerization of monomers with dimethyldiallylammonium chloride (DMDAAC) were also studied. The results showed, the obtained monomers had the expected structures, the yields were 70%~95%, and could be copolymerized with dimethyldiallylammonium chloride (DMDAAC) to obtain the novel polymers of modified PDMDAAC with the reactive functional group which could be used for dye-fixatives on cotton.
