  • Stabilizer polymerization process and process for making polymer polyols
    Patent number: 9644097
    Abstract: A polymeric stabilizer is produced by copolymerizing an unsaturated polyether with an unsaturated low molecular weight monomer in a controlled radical polymerization. The polymeric stabilizer is useful for producing polymer polyol products via a mechanical dispersion process or an in situ polymerization process.
    Type: Grant
    Filed: April 22, 2012
    Date of Patent: May 9, 2017
    Assignee: Dow Global Technologies LLC
