Abstract:
The present invention is drawn to a surfactant initiator. The surfactant initiator includes a first hydrophilic chemical group bonded to a first hydrophobic chemical group to form a first portion. A second portion is also included, made up of a second hydrophilic chemical group bonded to a second hydrophobic chemical group. A homolytic cleavable group chemically bonds the first and second portions. At least one of the first and second portions is configured to initiate free-radical polymerization upon separation of the homolytic cleavable group. Such surfactant initiators can be used to produce latex particulates and associated suspensions and inks.
Abstract:
The present invention is drawn to a method of preparing anti-oxidant-modified latex particulates, ink-jet inks, and coating compositions. The present invention is also drawn to related latexes and ink-jet inks. The method can include steps of generating an emulsion with a hydrophilic continuous phase and a hydrophobic discontinuous phase, wherein the hydrophobic discontinuous phase includes monomers for polymerization, at least one monomer being modified by an anti-oxidant moiety; and polymerizing the monomers in the hydrophobic discontinuous phase using a biocatalytic polymerization process.
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.
Abstract:
Bistable molecules are provided with at least one photosensitive functional group. As thus constituted, the bistable molecules are photopatternable, thereby allowing fabrication of micrometer-scale and nanometer-scale circuits in discrete areas without relying on a top conductor as a mask. The bistable molecules may comprise molecules that undergo redox reactions, such as rotaxanes and catenanes, or may comprise molecules that undergo an electric-field-induced band gap change that causes the molecules, or a portion thereof, to rotate, bend, twist, or otherwise change from a substantially fully conjugated state to a less conjugated state. The change in states in the latter case results in a change in electrical conductivity.
Abstract:
The present invention is drawn to a method of generating functionalized latex particulates in a colloidal suspension. The method can comprise steps of protecting functional groups present on polymerizable monomers with photo labile groups to form protected monomers; polymerizing the protected monomers to form a protected polymer; and exposing the protected polymer to a wavelength of light that removes the photo labile groups from the functional groups, thereby forming the functionalized latex particulates. These latex particulates can be used in a wide variety of applications, including in ink-jet ink printing applications.
