Mechanism and Modeling of EmulsionPolymerization: New Ideas and Concepts -1. Particle Nucleation

摘要

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