Synthesis of sodium polyacrylate copolymers as water

2021-2-5 · However, in wet ultrafine grinding of ceramic pigment particles, there is little research on the use of water-based dispersant containing solvated chains (i.e., methyl methacrylate) as a dispersant or a grinding aid. The steric hindrance effect of solvated chain as a solvate outer layer on particle surface is still unclear.
