  • Process for the preparation of monodisperse polymer particles
    Patent number: 9309368
    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: January 10, 2014
    Date of Patent: April 12, 2016
    Assignee: LIFE TECHNOLOGIES AS
