St-MA-AA酯化改性高分子分散剂的合成与应用
Synthesis and application of partially esterified St-MA-AA as polymer dispersant
摘要
Abstract
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%.关键词
