Summary: New experimental data for nucleation in emulsion polymerization prove that the process is heterogeneous in nature so that water‐borne oligomers precipitate at the surface of monomer drops. The particle morphology at the early stage of the process is strongly influenced by the initiator concentration. The hydrophilicity of the monomer is less important as methyl methacrylate, styrene, and 4‐tert‐butyl styrene show similar behaviour.
