The mechanism of core- shell emulsion polymerization was brifly introduced, which included grafting, interpenetrating network formation and ionic bonding. The effects on the structure of core - shell emulsion latex and properties of the polymer were described in details. The effects on the structure of core - shell emulsion latex include polymerization process, hydrophilicity of monomer and properties of initiator.The effect on the properties of the core - shell polymer included dosage of monomer, initiator and core - shell polymer were outlined in the following field ： coating with high performance, anti - penetrating materials, anti - impact modifiers and preparation of toughner.
