摘要:
Ion-conducting (co)polymer media and ion-conducting oligomer media close in ion conductivity to organic-solvent-based electrolytes can be produced easily and safely on industrial scale. These ion-conducting (co)polymer media use (co)polymers containing at least one cyclocarbonato group, and these ion-conducting oligomer media employ oligomers containing at least two cyclocarbonato groups.
摘要:
A solidifying material for a cell electrolyte solution is a block copolymer, which comprises, as segments A, a polymer non-compatible with the cell electrolyte solution and, as segments B, a polymer compatible with the cell electrolyte solution. The solidifying material absorbs and solidifies the cell electrolyte solution. A smallest unit of the block copolymer is A-B-A. To each of the segments B, at least one group selected from the group consisting of a carboxyl group, an ester group, a hydroxyl group, a sulfonic group, an amino group, a cyclic carbonate group and a polyoxyalkylene group is bonded via a —S— bond or a —C— bond.

摘要:
A high-molecular gelling agent precursor for an electrolyte comprises a copolymer formed of (A) a hydrophobic monomer having a hydrophobic group, which forms a carboxyl group upon saponification, and (B) a hydrophobic polyfunctional monomer. The saponification product of the copolymer has property to gel the electrolyte. A high-molecular gelling agent for the electrolyte is produced by saponifying the precursor with a saponifying agent selected from the group consisting of acids and alkalis while using a reaction medium selected from the group consisting of water and hydrophobic organic solvents.

Disclosed are an alkoxysilyl-containing A-B block copolymer formed from (meth)acrylate monomers as constituent monomers, characterized in that a polymer block of A chain has a number average molecular weight (Mn) of from 1,000 to 50,000 and a molecular weight distribution (Mw/Mn) of not greater than 1.6, a polymer block of B chain comprises alkoxysilyl-containing (meth)acrylate units as constituent monomer units, and the A-B block copolymer as a whole has a molecular weight distribution of not greater than 1.6, a process for the production of the block copolymer, a resin-treated pigment, and a pigment dispersion.

摘要:
Disclosed are an aqueous pigment dispersion containing at least a pigment, water, a high-molecular dispersant, and an alkali. The high-molecular dispersant is a diblock polymer having a formula (1) of A-B or a triblock polymer having a formula (2) of A-B-C. The diblock or triblock polymer is a diblock or triblock polymer obtained by polymerizing addition-polymerizable monomers with a radical generator while using an organic iodide as a polymerization initiating compound and an organic phosphorus compound, organic nitrogen compound or organic oxygen compound as a catalyst. Also disclosed are a production method and use of the aqueous pigment dispersion. With the high-molecular dispersant obtained by a simple living radical polymerization process free of the problems of conventional living radical polymerization and having a precisely-controlled molecular structure, the aqueous pigment dispersion can be obtained with the pigment dispersed in it.
