摘要
在二氯甲烷中使丙烯酰氯与1-氨基蒽醌(1-AQ)反应合成了反应性1-丙烯酰胺基蒽醌(N-AQ)黄色染料,采用傅里叶变换红外光谱(FT-IR)和质子核磁共振(1H NMR)对其进行表征,表明制得的N-AQ结构明确。进而通过分散聚合法,使N-AQ与甲基丙烯酸甲酯(MMA)共聚,成功制备了黄色P(MMA-co-N-AQ)聚合物微球。由扫描电子显微镜(SEM)和zeta电位及粒度分析仪对微球的形态、大小及分布进行了表征,并利用可见光-紫外光谱仪(UV-Vis)对微球中引入的N-AQ含量进行了定量分析。结果表明,反应性染料的转化率达93.6%,在聚合反应中改变N-AQ的用量,可将所制备的微球粒径控制在1.3～3μm之间,球形完好、表面光滑、粒径均一,可望应用于彩色激光打印。
The yellow dye, N-（9,10-dioxo-9,10-dihydro-anthraeen-l-yl）-acrylamid （N-AQ） was obtained hy reaction of 1-aminoanthraquinone with acryloyl chloride in dichloromethane. The N-AQ structure was characterized by Fourier transform infrared spectroscopy （FT-IR） and proton nuclear magnetic resonance （1H NMR）. The results show that N-AQ has clear structure. The yellow P（MMA-co-N-AQ） microspheres were prepared via dispersion polymerization using methyl methacrylate （MMA） and reactive N-AQ. The shape, size and uniformity of P（MMA-co-N-AQ） microspheres were characterized by scanning electron microscopy （SEM） and zeta potential and particle size analyzer. The amount of N-AQ in microspheres was analyzed by ultraviolet-visible absorption spectrometry （UV-Vis）. The result showed that the conversion rate of reactive N-AQ reaches 93.6% The diameter of resulting microspheres was controlled in range from 1.3- 3μm with changing N-AQ amount in feed. It was found that resulting yellow microspheres have surface smooth and particle size uniform, will be expected to apply in color laser printing.
