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.
