Salt-Tolerant Star Macromolecules
The present invention relates to multi-arm salt-tolerant star macromolecules, and methods of preparing and using the same. In one aspect of the invention, a salt-tolerant star macromolecule is capable of providing salt-tolerance to an aqueous composition.
THE AMPHIPHILIC POLYMER
The present application relates to an amphiphilic polymer and a method of preparing the same.
Furthermore, the present application relates to a micelle including a drug encapsulated by the amphiphilic polymer and a composition including the same.
The amphiphilic polymer according to the present application has excellent drug encapsulation properties as well as good dispersion properties in an aqueous solution.
Copolymer formulation for directed self-assembly, methods of manufacture thereof and articles comprising the same
Disclosed herein is a composition comprising a block copolymer; where the block copolymer comprises a first polymer and a second polymer; where the first polymer and the second polymer of the block copolymer are different from each other and the block copolymer forms a phase separated structure; an additive polymer; where the additive polymer comprises a bottlebrush polymer; and where the bottlebrush polymer comprises a polymer that is chemically and structurally the same as one of the polymers in the block copolymer or where the bottlebrush polymer comprises a polymer that has a preferential interaction with one of the blocks of the block copolymers; and a solvent.
Processes for nanoparticle dispersions with ionic liquid-based stabilizers
The disclosure generally relates to a dispersion of nanoparticles in a liquid medium. The liquid medium is suitably water-based and further includes an ionic liquid-based stabilizer in the liquid medium to stabilize the dispersion of nanoparticles therein. The stabilizer can be polymeric or monomeric and generally includes a moiety with at least one quaternary ammonium cation from a corresponding ionic liquid. The dispersion suitably can be formed by shearing or otherwise mixing a mixture/combination of its components. The dispersions can be used to form nanoparticle composite films upon drying or otherwise removing the liquid medium carrier, with the stabilizer providing a nanoparticle binder in the composite film. The films can be formed on essentially any desired substrate and can impart improved electrical conductivity and/or thermal conductivity properties to the substrate.
Compound having azo skeleton structure, pigment dispersant, pigment composition, pigment dispersion, and toner
The present invention provides a compound and a pigment dispersant, each of which improves the dispersibility of various types of pigments in a non-aqueous solvent and also provides a pigment composition, a pigment dispersion, and a toner, each of which has a preferable coloring power. The compound includes a polymer which has a monomer unit having a specific structure and also includes a specific partial structure.
Pressure sensitive adhesive composition
Provided are a pressure-sensitive adhesive composition, a protection film, an optical laminate, a polarizing plate, and a display device. Provided is the pressure-sensitive adhesive composition which is excellent in various physical properties, such as endurance reliability, has excellent antistatic characteristics that change little over time. The pressure-sensitive adhesive composition can be used for a protection film, or can be used for an optical film, such as a polarizing plate, for example.
