ABSTRACT:
A non-aqueous absorbent comprising a crosslinked polymer which contains a structural unit having a carboxyl group and/or a sulfonate group in an amount of 20 to 100% weight in its molecule and in which from 30 to 100% by mol of the protons in the carboxyl group and/or the sulfonate group have been substituted by onium cations; a non-aqueous gel made of this non-aqueous absorbent and an organic solvent; and a non-aqueous absorbent sheet and a non-aqueous absorbent agent containing the non-aqueous absorbent. Because of having excellent capabilities of absorbing and holding various organic solvents such as alcohols and gelating, these materials are usable for various purposes, for example, lithium batteries, alcohol-based bactericidal materials or alcohol-based bactericides, cold insulating materials or cold insulators, gel sheets for cooling, fuel compositions for solid fuels or solid fuels using the same, fragrance materials or fragrances, patch materials or patches, insecticidal compositions or insecticides, fuel stores for fuel batteries or fuel batteries using the same.
