Abstract: Influence of monomer-feeding method, initiator type, dosage of composite emulsifier and polymerization temperature etc. on particle size of the core-shell emulsior! particles was investigated. Thus, an acrylate emulsion with multi-layer core-shell structure having solid content 42% and average particle size 64. 9 nm with narrow distribution was synthesized at 50 ℃ by using continuous feeding technique a composite emulsifier at low concentration, and a high-efficient initiator at low reaction temperature.
