The core-shell composite particle is varied from a core-shell structure to a complete phase separation with various two phase structure in between, depending on polymerization sequence, polymerization methods, reaction condition, polymer compatibility, molecular weight of polymer, polymer phase ratio, etc. Reagent grade Styrene (St), Methyl methacrylate (MMA), Ethyl acrylate (EA) was distilled at reduced pressure under N2 atmosphere. 2 - hydroxyethyl methacrylate (2-HEMA) as functional monomer was obtained. And Ammonium persulfate (APS) as initiator was obtained from Aldrich. Sodium dodecyl benzene sulfonate (SDBS) as an emulsifier was used without purification. |
