The acrylate copolymer emulsion with core-shell structure was successfully prepared via pre-emulsified semi-continuous seeded polymerization using SDS and OP-10 as compound emulsifier, and methyl methylacrylate (MMA), butyl acrylate (BA) and dodecafluoroheptyl methacrylate (DFMA) as main monomers. SEM and OCA were used to characterize the structure and the product, meanwhile, the influence of core-shell monomer ratio, the dosage of emulsifier, initiator and fluoride monomers on the reacting

... uct properties were studied. Obvious ball structure could be seen clearly by the scanning electron microscopes when the hard monomer MMA matched with a moderate amount of DFMA as the shell in an optimized reaction condition. Detected with the help of particulate size description analyser, the latex particle which had uniformly size was found mono-dispersed.
