  • Method for the preparation of low odor copolymer latexes
    Patent number: 8691937
    Abstract: A method of preparing a low odor polymer latex composition includes the step of polymerizing a monovinylidene monomer, such as styrene, and a conjugated diene, such as butadiene, in the presence of a linear alkyl thiol chain transfer agent. The resulting polymer latex is treated with an oxidizing agent to oxidize residual chain transfer agent to volatile decomposition products that are then removed by steam stripping.
    Type: Grant
    Filed: December 16, 2010
    Date of Patent: April 8, 2014
    Assignee: Styron Europe GmbH
    Inventors: Bernard Fouchet, Gerold Lohmueller, Patric Eckerle
