It was pointed out that proper grafting of monomer onto protective colloid was vital to stabilityofcolloid particle. So it is important to properly use protective colloid in emulsion polymerization.
The results indicated that fluorine pollution strengthened the stabilityof soil colloid and increased the critical flocculation concentration.
结果表明，氟污染使土壤黏粒的稳定性增强，土壤胶体的临界聚沉浓度增大；

The effect of coconut amine on the viscosity and stabilityof residue asphaltene system was studied and the change in viscosity and colloidstability with coconut amine content was discussed briefly.
