  • Method for making odorless aqueous solutions of water soluble polymers or copolymers
    Patent number: 4839417
    Abstract: Water-soluble polymers or copolymers of acrylic and/or methacrylic acid which contain at least 50 base mole percent of these acids and as end groups hydrogen atoms, hydroxyl groups and moieties of a water-soluble mercaptan or moieties with a sulfoxide group formed therefrom are produced in a readily reproducible manner and free of mercaptan odor in aqueous solution by polymerization with an initiator system consisting of hydrogen peroxide, a water-soluble mercaptan and an iron salt and used as calcium-binding additives or as dispersants in aqueous systems.

  • Continuous emulsion polymerization process
    Patent number: 4713434
    Abstract: A process for the continuous preparation of aqueous plastic dispersions which comprises emulsifying one or more free-radically polymerizable monomers in an aqueous phase in the presence of an emulsifying agent, in an agitator vessel; initiating the free-radical polymerization of said monomer or monomers in said aqueous phase; and passing said aqueous emulsion of the free-radically polymerizing monomer or monomers through a tubular reactor whose internal surface comprises an (optionally fluorinated)saturated polyolefin.
