以苯乙烯(St)、马来酸酐(MA)、丙烯酸(AA)为单体,采用溶液聚合法合成三元共聚物,并用正丁醇作酯化剂,对其进行部分酯化,制备出高分子分散剂 St-MA-AA 部分酯化物。将此分散剂应用于酞菁蓝颜料表面改性处理上,讨论了单体摩尔配比、分子量分布等因素对颜料平均粒径、Zeta 电位、分散性(DE)和相对着色力(Kr)的影响。结果表明,St、MA、AA单体最佳摩尔比为1∶1∶0.5时,自制分散剂St-MA-AA部分酯化物与市售分散剂SMA1440相比,颜料的平均粒径降低了15%,Zeta电位上升了13%,离心稳定性升高了77%,着色力增加了9%,分散效果明显更好。

A polymeric dispersant was prepared from styrene,maleic and crylic acid as monomers by solution polymerization and partial esterification with n-butanol. The surface modification treatment of copper phthalocyanine pigment by polymeric dispersant was studied. The influences of molar ratio, molecular size on properties of particle size of the pigment,Zeta potential,dispersity (DE) and relative tinctorial strength (Kr) were disscussed. The optimum molar ratio of St,MA,AA was 1∶1∶0.5. The self-made partially esterified St/MA/AA had better results on pigment dispersion than SMA1440,e.g., the average particle size of the pigment was reduced by 15%,Zeta potential increased by 13%, centrifugal stability increased by 77%,tinctorial strength increased by 9%.
