The invention relates to a method for producing particles of mineral material comprising grinding of at least one mineral material in the presence of water. The grinding according to the invention is carried out in the presence of at least one polymer obtained by a radical polymerization reaction of a partial sodium salt of itaconic acid and partial decarboxylation of the polymer obtained followed by partial or total neutralization of the decarboxylated polymer. The invention also relates to an aqueous composition comprising particles of ground mineral material and such a polymer, in particular a mass-loading composition for the production of paper or a paper-coating-colour composition.

Disclosed is preparation of a freestanding ion gel having high stability and high ionic conductivity based on surface-activity ionic liquids. Further, disclosed is a solid electrolyte using the ion gel. A method for preparing the freestanding ion gel include mixing a surface-activity ionic liquid having an alkyl group having 8 or greater carbon atoms, a crosslinking agent, water and oil with each other to form a bicontinuous microemulsion mixture; ii) adding an initiator to the mixture; and iii) curing the mixture using ultraviolet (UV) or thermal energy to form a freestanding ion gel.

A Polymer used as a treatment means, having an acid number greater than 100. The Polymer has a valent metal ion which is bonded to at least one reactive group. The characteristics of the Polymer include, conductivities of 4 S/cm to 200 S/cm or more, depending upon the concentration and nature of the metal bound. The conductivity proportional to the amount of metal bound, the ability of the Polymer to bind metals having a +1, +2, +3, +4, or +5 valence charge to the Polymer, and the ability to bind two or more different metals to separate binding sites on the Polymer.

The present invention relates to soluble aqueous compositions comprising metal salts of selected polyitaconic acid (PIA) resins.

A process for preparing a composition by free-radical polymerization of a monomer composition comprising: a) at least one ethylenically unsaturated carboxylic acid containing monomer or anhydride thereof; b) optionally at least one ethylenically unsaturated monomer different from a) but copolymerizable therewith; and c) at least one crosslinking monomer containing at least two ethylenically unsaturated groups. The monomer composition is polymerized in an organic medium having a solubilizing effect on one or more of the monomeric ingredients, but substantially none on the resulting polymer. The polymerization is conducted in the presence of a free radical forming catalyst and at least one steric stabilizing polymer polymerized from a vinyl lactam and a copolymerizable monomer selected from a short chain alkyl ester of (meth)acrylic acid, a long chain alkyl ester of (meth)acrylic acid, and combinations thereof.
