| 摘 要： | Soap-free emulsion copolymerization of styrene （St） and sodium sulfonate styrene （NaSS） could yield homodisperse sulfonate-containing particles with clean surface. But the incorporation of NaSS could never be increased beyond 2.6 % by weight in the conventional batch and seeded emulsion copolymerization in the ab- sence of emulsifier because large amounts of soluble polyelectrolyte would unstablize the reaction system if ex- cessive amount of NaSS was used. In our work, semi-continuous copolymerizations were carried out in the presence of mixed emulsifiers, and a new method to purify the latex polymer was developed. The influences of the NaSS mole ratio in the total monomers and the monomer addition time on the S content in the purified copolymer were investigated by elemental analysis.
