The organosilicon modified acrylate polymer latex was synthesized by the seeded semicontinuous emulsion polymerization and its particle size distribution was analyzed.The results showed that organosilicon modified acrylate polymer latex with the solid content 42wt%,emulsifier content 4wt%(based on monomer quantity),narrow distribution nanometer particles has been prepared.The particle-size distribution grows narrow,the average size increases gradually with the reaction.Along with SDS and the OP-10 mole ratio in the emulsifier mixture reduction,the particle size increases.
