文摘

The acrylamides copolymers PMBAs were designed as dispersants based on the amino groups as anchoring groups and alkyl groups as solvent chains. Yellow iron oxide dispersion achieved excellent colloidal stabilization and dispersity at PMBAs’s presence by steric stabilization. Yellow iron oxide dispersion obtained high fluidity and low viscosity fluid with high solid content with a small amount of PMBAs. PMBAs showed outstanding dispersing ability might be a prospect in material dispersing area.
