Specifically, at least one phase is a dispersed phase and one phase in a continuous phase. The treatment chamber has an elongate housing through which the phases flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the phases within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other.

  • Patent number: 7910649
    Abstract: The present invention is drawn to the use of blocked maleimide monomers for the preparation of latex particles, including those having active maleimide surface groups. In accordance with this, a method of forming latex particulates can comprise the steps of preparing a monomer emulsion including an aqueous phase and an organic monomer phase, wherein the organic monomer phase includes at least one blocked maleimide monomer; polymerizing the organic monomer phase to form blocked maleimide latex particulates dispersed in the aqueous phase; and unblocking the blocked maleimide latex particulates to form latex particulates with active maleimide groups at least on the surface of the latex particulates.
