Influence of Polymer Dispersant With Different Contents of Anchoring Group on the Dispersion of Pigment Violet 23
The anchor group of polymeric dispersants absorbed onto the pigment surface
aiding in improving the stability of the pigment suspension. The content of anchoring groups affects the adsorption effectiveness of the dispersant and the stability of the pigment. In this study
a series of polymeric dispersants with varying contents of anchoring group were prepared
via
solution polymerization
using different additions of styrene and hydroxy polyethylene glycol methacrylate (HO-PEG-MA). These dispersants were employed for the dispersion of pigment violet 23. The particle size
storage stability
and surface adsorption capacity of pigment suspension were characterized. When the molar ratio of styrene to hydroxy polyethylene glycol methacrylate was 3:1
the particle size of pigment suspension was 191.3 nm and the stability of pigment suspension was optimal.
