New series of slightly crosslinked and reactive polycationic dye-fixatives for cotton fabric were synthesized by copolymerization of 3-chloro-2-hydroxypropyltriallyl-ammonium chloride (CHTAAC) and dimethyldiallylammonium chloride. The structures of obtained dye-fixatives could be controlled by varying molar ratios of raw-materials of CHTAAC to DMDAAC during polymerization and their molecular weights were possibly controlled by adjusting different polymerization conditions. The results showed,
