  • Process for the preparation of monodisperse polymer particles
    Patent number: 8658733
    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.
    Type: Grant
    Filed: October 10, 2012
    Date of Patent: February 25, 2014
    Assignee: Life Technologies AS
