Synthesis of block copolymer poly (n-butyl acrylate)-b-polystyrene by DPE seeded emulsion polymerization with monodisperse latex particles and morphology of self-assembly film surface

► Block copolymer was firstly synthesized by DPE seeded emulsion polymerization. ► Monodisperse latex particles were obtained resulting from monomer swollen into seeded latex and DPE mechanism. ► High conversion and high solid content are beneficial for industrial application. ► Film with phase separation was got and potential for preparation of nanostructure materials.
