摘要
The monodispersed copolymer microspheres were prepared by soap free emulsion copolymerization from methyl methacrylate(MMA), butyl acrylate(BA) and acrylic acid(AA). The microspheres have an average diameter d p=1 10 μm and monodispersity C v=2 02%. The monodispersed core shell copolymer microspheres having average diameter d p 1 14 μm and C v 1 18% were then prepared by seeding polymerization. It is confirmed from the number of seed microspheres and core shell microspheres that the polymerization of shell monomers was carried out only on the seed microspheres.
