Abstract

Acryl and vinyl sulfone functionalized blue and orange azo dyes were prepared by the coupling reaction of 6-bromo-2-cyano-4-nitroaniline and 2,5-dimethoxy-4-(vinylsulfonyl)benzenamine with 3-acrylamido-(N,N-diethylamino)benzene and 3-methyl-(N,N-diethylamino)benzene, respectively, for the coloring of poly(methyl methacrylate) (PMMA). Allyl functionalized dye was also prepared by reacting vinyl sulfone-containing dye with allylamine. Three types of dyeing method were used: the copolymerization of reactive dye with methyl methacrylate (MMA) and dyeing by polymerization of MMA in the presence of polymeric dye and dye 2 without reactive function. The color fastness for the three PMMAs were evaluated by comparing the solubility of dye under various conditions.
