Process for the preparation of monodisperse polymer particles

USPTO Application #: 20070265390
Title: Process for the preparation of monodisperse polymer particles
Abstract: A process for the preparation of monodisperse polymer particles which are formed by contacting monomers with aqueous dispersions comprising monodisperse swellable seed polymers/oligomers, and initiating polymerization in the presence of a steric stabilizer. The resulting swollen seed particles are characterized by the particle mode diameter. (end of abstract)
