  • Patent number: 8742047
    Abstract: A multifunctional polymerizable ionic liquid is described comprising an anion and a cationic group having at least two ethylenically unsaturated polymerizable groups, each bonded to the cationic group via a divalent non-alkyl linking group. The multifunctional linking groups independently comprise a heteroatom such as oxygen or nitrogen. The linking groups may independently comprise one or more linkages such as an amide, urea, or ether linkage and more typically a urethane or ester linkage. The ethylenically unsaturated polymerizable groups are typically (meth)acrylate groups. Coatings and coated articles are also described.

  • Patent number: 7465765
    Abstract: The present invention is drawn to compositions and methods of generating epoxide group-functionalized latex particulates in a liquid suspension, as well as compositions and methods of preparing ink-jet inks. Steps of the methods can include forming an emulsion including a continuous hydrophilic phase and a discontinuous hydrophobic phase, wherein the discontinuous hydrophobic phase includes a plurality of monomers. The plurality of monomers can comprise epoxide group-forming monomers and support-forming monomers. Other steps include copolymerizing the monomers to form precursor latex particulates dispersed within the hydrophilic phase, and reacting the precursor latex particulates with a base to form epoxide group-functionalized latex particulates. These latex particulates can be used in a wide variety of applications, including in ink-jet ink printing applications.

  • Patent number: 4379913
    Abstract: Chain extended random alkoxylated polyols having branched configurations are useful as internal antistatic additives for polymeric structures. A polyol having a branched configuration is alkoxylated with a mixture of ethylene oxide and propylene oxide and then chain extended to produce a high viscosity fluid additive which is compatible as a dispersed phase with polymer melts and does not agglomerate or separate from the melt during spinning. From about 0.1% to about 15% by weight of the additive is incorporated in polymeric structures as an antistatic agent. A useful additive composition is obtained using pentaerythritol tetrapropoxylate as the polyol and Bisphenol A diglycidyl ether as the difunctional reactant.
