  • POLYMERIZABLE IONIC LIQUID COMPRISING MULTIFUNCTIONAL CATION AND ANTISTATIC COATINGS
    Publication number: 20120149800
    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.

    Abstract: Presently described are curable compositions comprising a mixture of at least one (e.g. free-radically) polymerizable ionic liquid and at least one other ethylenically unsaturated monomer, oligomer, or polymer. The polymerizable ionic liquid is characterized as having an air to nitrogen curing exotherm ratio of at least 0.70. Also described are articles and methods of making articles from such curable compositions. A monofunctional polymerizable ionic liquid is also described comprising a non-polymerizable substituted imidazolium cationic group and a polymerizable sulfonate anion.
